What ages are MontiiCo bottles and cups suitable for?

MontiiCo Original Bottles
Our original bottles have a wide mouth opening (4.7cm) which is perfect for popping icecubes in to keep your drink uber frosty! It does mean that younger children might need supervision while using their MontiiCo bottle though, or while they adjust to the wider opening – in case of spills. The screw top lid is easy to open and close, thanks to the cool handle that gives a little bit more leverage. We recommend Montii bottles for Children aged 4 and up. (And adults of course!)
MontiiCo Mini Bottles
Our Mini bottles are suitable for all ages. They still come with the wide mouth opening we know and love (which means the lids are interchangeable!), but the sports pop-top make them more suitable for all ages.
MontiiCo Smoothie Cups
Mrs Smoothie cups come with a straw top and are suitable for all ages, however we do recommend that an adult fills the cup and ensures the lid is shut tight!

Do MontiiCo bottles and cups leave condensation marks?

Our bottles and cups are double walled – meaning NO condensation forms on the outside of the bottle. None. Zilch. Nada. No need for a coaster on your desk, no damp inside your handbag – and best of all – no drips on your shirt while you swig from Montii on your way to the beach!

Are MontiiCo bottles suitable for hot drinks?

All of our bottles are double-walled, vacuum insulated (also known as thermally insulated), meaning they are suitable for hot and cold drinks – perfect for year round use. The wide mouth opening does mean you need to be EXTRA careful with hot liquids.

MontiiCo bottles provide 12 hours of warming. Some tips to get max warming:

Pre warm the bottle just prior to use with boiling water. Attach lid and let stand for 10 minutes, then empty
After pre warming, fill your bottle, and replace lid for maximum insulation efficiency
Keep lid in place as much as possible to keep your beverage warm
WARNING: Always exercise caution with hot beverages to avoid burns and scalds. Wide mouth bottles are NOT recommended for use to serve hot beverages to children.

What are MontiiCo bottles and cups made from?

MontiiCo bottles are made from Stainless Steel (18/8 and 304), with a kid safe, scratch and dent resistant finish. Our original lid is also Stainless Steel, with an engraved bamboo topper and small silicone ring to ensure a water-tight seal.
Our sports lid is made from BPA-free polypropylene (pp#5).
The MontiiCo smoothie cups are made from Stainless Steel (18/8 and 304), with the same kid safe, scratch and dent resistant finish. The lid on our smoothie cups has a BPA-free polypropylene (pp#5) inner.

Do MontiiCo bottles and cups come with a warranty?

Our products are constructed with durable, long-lasting materials to ensure a consistent high level of quality. 

Our products have a manufacturer's warranty of six months. This covers any manufacturing defects such as issues with parts or materials, with proof of purchase. Wear and tear, and care issues including ripping, spills, mould and stains (i.e issues NOT caused by a fault in the manufacturing process) are not covered under manufacturer warranty. 

If you find your product has a manufacturing fault, please email us at support@montii.co as soon as possible, so we can work with you to find a resolution. We want you to love your MontiICo & Lunch Punch products and pride ourselves on going above and beyond for our customers!

We may ask that you return your items so that we can conduct a thorough investigation before a replacement/refund is given. 

Please supply us with your order number or proof of purchase and photos of the fault when you email us at support@montii.co 

How do I wash my MontiiCo bottles and cups?

Wash and rinse bottle thoroughly before first use, and after each use. Hand washing is recommended for best results. Putting your bottle in the dishwasher may dull the colour, damage the finish and void your warranty.

Bamboo is a renewable natural product, there will always be natural variations in colour, tone and grain ensuring no two MontiiCo bottle lids look exactly the same.

NEVER put the bamboo lid in the dishwasher. Putting your bamboo lid in the dishwasher WILL damage the finish and void your warranty. Hand wash only and always air dry thoroughly.

How do I store my MontiiCo bottles and cups?

Always store your MontiiCo bottles and cups empty, and completely dry inside. We recommend storing your empty bottles without the lid affixed.

Do I have rust stains on my bottle?

All MontiiCo products are made from 18/8 food-grade stainless steel. This food-grade stainless steel is highly rust resistant, as well as safe, durable and BPA-free. Sometimes marks can be left behind from the electropolishing process which smooths the surface of the metal as electrolytes left on the surface can turn a rust colour, but this is perfectly normal and harmless.

To remove residue, we recommend that you leave your bottle/cup/food jar to soak overnight with hot water and baking soda or white vinegar. After soaking, give your bottle/cup/food jar a really good scrub using a bottle brush or a scouring pad. Let us know how you get on after trying this method!

Why is my insulated bottle rattling?

If you hear a rattle in your bottle, it can be one of two things: either the weld (or a piece of it) that retains the integrity of the vacuum space has become dislodged and is now rattling in the space between the double wall insulation, or a small piece of metal called the “getter” has broken free and is now moving about freely at the base of your bottle. You can continue to use your bottle normally, it is still completely safe.

Both of these components have their respective functions within the internal walls of the bottle. A loose getter will not affect the insulation properties of the bottle whereas a broken weld or piece of it can potentially render the insulation useless because the vacuum seal can be compromised.

To check if the vacuum seal is still in tact, first ensure your bottle is completely empty and dry, then place you ear next to the opening and listen for a humming sound. If you can hear it, your seal is still in tact!

Do you sell replacement parts for my MontiiCo bottle or cup?

Yes! We sell replacement caps and straws on our website.

What do you consider normal wear and tear?

With normal wear and tear and daily use, paint can chip as a result of abrasion, scratching and impact (i.e. bottles falling out of a bag, etc.) The paint MontiiCo uses is an acrylic-based that is lead free, BPA-free and free from toxic chemicals.

If paint is flaking or peeling off, please submit a warranty claim and we'll issue a replacement.

To reduce wear and tear and prolong the life of your MontiiCo bottles and cups, we recommend hand washing painted bottles with mild, biodegradable detergent. The high water pressure and temperature in dishwashers can cause painted bottles to chip over time.

What does insulated mean?

To make an Insulated MontiiCo bottle, we first construct an inner and outer bottle, which are sealed together and welded shut to be completely air-tight. Then the bottle is connected to a high-power vacuum pump which removes all the air from the gap in between the inner and outer bottle. Since there’s nothing to conduct heat across the gap, vacuum insulation is more effective than foam or other common insulating materials like Styrofoam, a derivative of plastic. Vacuum insulation works so well, it is the technology of choice for cryogenic storage tanks and other high-performance insulating vessels. Our vacuum insulated bottle can keep your beverages hot or cold for hours and hours.

Why does my MontiiCo bottle have a metallic taste?

MontiiCo products are made from durable 18/8 stainless steel. The stainless steel that we use to manufacture our products is the same grade that is used most commonly in the food, beer and wine industries because it is easy to clean, durable, and does not impart flavours or leach chemicals into the beverage contents.

If you have a metal allergy or sensitive palate, you may detect a metallic taste. Please let us know what product and cap you’re using – sometimes swapping out the lid to a Sports lid is a great solution, since those caps are Polypropylene and create a barrier between your mouth and the bottle itself.

We also recommend soaking your bottle overnight with hot water and baking soda. Follow the soak with a good scrub using a bottle brush or the abrasive side of a dish scouring pad aided by a wooden spoon or other kitchen utensil for leverage. This usually works to remove any lingering tastes/ residues.

Can I put my MontiiCo bottle in the freezer?

No. The force of liquids expanding as they freeze can cause your MontiiCo bottle to become deformed and can also break the weld that holds the bottle together, so we strongly advise against it. Freezing any MontiiCo bottle or cup will void your manufacturers warranty.

I dropped my MontiiCo bottle and dented it. Is there any way to get the dents out?

MontiiCo products are made of durable 18/8 stainless steel. Unfortunately, they can dent when dropped. Our warranty covers manufacturer's defects only, not damage caused by using or dropping your bottle.

Even if you've dented your bottle, it's still totally safe to continue to use. With no plastic liner on the inside, a dent, no matter how large, will not change the composition of the metal nor make it unsafe.

Do MontiiCo bottles and cups have a liner?

No. All MontiiCo products are made from high quality, 18/8, food-grade stainless steel. Stainless steel is naturally free of BPA and other harmful substances.

Stainless steel is inherently safe for food and beverage contact; plastic or epoxy linings are not necessary. This is one of the main differences between a stainless steel MontiiCo and aluminum bottles. All aluminum bottles must have a liner to maintain the integrity of the contents inside the bottle; otherwise, the aluminum leaches into the contents, which is unsafe.

What is stainless steel and what does 18/8 stand for?

Stainless steel is an iron-containing alloy made from some of the basic elements found on earth: iron ore, chromium, silicon, nickel, carbon, nitrogen and manganese. The properties of the final metal change depending on varying amounts of these elements. There are over 150 grades of stainless steel, of which 15 are most commonly used.

MontiiCo products are constructed from high-quality, 18/8, food-grade stainless steel. The numbers stand for the percentages of chromium and nickel in the steel, 18% and 8% respectively. Chromium increases the metal's hardness and nickel gives it strength. Together they also make stainless steel highly resistant to stain or rust.

Stainless steel is easy to clean, durable, inert and sanitary. That's why it's the material of choice among the food, beer and wine industries.

Does the paint on MontiiCo bottles contain lead?

No way. All MontiiCo painted products are nontoxic, safe and durable.

Can I fill my MontiiCo bottle or cup with acidic beverages such as orange or apple juice?

Yes. Acidic beverages will not corrode or damage the high-quality stainless steel.

Can I use a MontiiCo bottle for milk, breast milk or formula?

Absolutely. Your MontiiCo is food-grade stainless steel, which is safe and will not retain or impart flavours.

Can I put my MontiiCo bottle or cup on a stove?

Heating an MontiiCo bottle or cup is not advised, will damage the painted finish and bottle, and voids the warranty.

Are the MontiiCo bottle lids interchangeable?

Yes! The original and sports caps are interchangeable. How rad is that!
