FAQs
Does Dumbo work when the bottle is empty?
Yes! Dumbo was designed to work as a secure mount whether the bottle is empty or full. Even the regular 24oz bottle is stable enough to hold an iPad when the bottle is empty.
What are the bottle made out off?
Our Dumbo Bottle are crafted using high-quality food-grade PETG plastic, ensuring your safety and peace of mind. They are meticulously designed to be 100% BPA-free, prioritising your health and well-being.
Can I leave my Dumbo in the fridge or freezer?
You can absolutely leave your Dumbo in the fridge overnight - that being said, due to the double-wall vacuum insulation, the cold of the fridge will only make the bottle cold, but will not necessarily reduce the temperature of the water inside. The insulation protects your drink from outside temperatures - which is why it keeps your cold drinks cold and your hot drinks hot when you're on the go.
If you want ice-cold water as quickly as possible, we recommend putting some ice cubes inside your bottle with cold water instead.
You definitely should NOT put your Dumbo in the freezer with the lid on (as liquid cools it expands in all directions. The expansion can cause the stainless steel walls of the bottle to deform and can sometimes also break the vacuum seal. If this happens your Dumbo will no longer
insulate properly).
As for putting your Dumbo in the freezer with the lid off - we wouldn't recommend that either - you're still better off putting ice cubes in the bottle for ice-cold water.
How long will Dumbo keep my drinks hot or cold?
Dumbo will keep your drink cold for 20 hours and hot for 12 hours thanks to its dual-wall vacuum-insulated stainless steel bottle.
Will Dumbo fit in my car's cupholder?
Dumbo was designed to fit in most cupholders. If you'd like to double-check, the diameter of the Regular bottle is 3.10 inches (78.6mm) and the diameter of the Large bottle is 3.33 inches (84.6mm).

What are the dimensions of the Magnetic Booster
The Magnetic Booster has an inner diameter of 44mm and an outer diameter of 55mm. It is 1.9mm thick.
Is the Magnetic Booster re-usable?
The Magnetic Booster was designed to be single-use - but if you're careful when removing it (doing so slowly, so that the adhesive stays on the magnetic ring), you can absolutely apply it to another device. We've done it dozens of times with our samples, and it retains its strong grip.
Can I use Dumbo with carbonated beverages?
No - We do not recommend using Dumbo with carbonated beverages - over time, the carbonation can cause pressure to build in the bottle, which may make the lid difficult to remove or forcefully eject and cause injury.
Is Dumbo patented?
Yes! Dumbo has design and utility patents across Europe and is a company based in London
The Dmbo looks simple on the surface but took over a year of engineering to perfect, so that it is stable when empty and gives you a full 90-degree range.
