We have fold tested the box 1000 times, and additionally, there is a two-year warranty. The fold lines are designed to bend in a specific direction, so it is important to follow the instructions in the folding guide.
The box is easy to fold, and the fold lines become more pliable with use. It is easiest to fold one side at a time. Make sure the corners fold inwards in the box. Press the sides in a little, and tip the lid over, so they catch the sides – start by tipping the lid over the back corners. Once the box is folded, attach the strap to the button on the box and wrap it around the box (going beneath the bottom and up) and close it on the front of the box. Remember the long flap should be facing out, so the “Uhmm” logo is placed on the lid of the box. See the folding guide under “product info”.

Yes, it is completely closed, and at the same time there are small holes where the lid joins to the box, which ensure that the food stays fresh. This means it is not 100% waterproof, and very runny liquids may leak out. However, the holes are so small that more viscous fluids like gravy, ketchup etc. do NOT leak out. If in doubt, we recommend that you place a small bag around the box’ exterior, as even tightly closed containers risk opening up.
It is both – the fold lines are soft and flexible, but the bottom, top and sides are hard, like an ordinary box.
No, the box keeps its shape when you open the lid. It is only once you press the sides, that it folds out like a plate.
The box has a matte surface, that makes it resistant to discolouring from food. Tomato sauce, carrots etc. clean off easily. If discolouring occurs from the likes of curry etc., we recommend you wash it twice. As the material is used/worn it will lose a little of its resistance.
No, our plastic material has a specific quality that means it does not retain any smell from food.
No, the box’s unique design allows the food to breathe, but the smell stays inside the box – even foods that have a very strong odour.
No, there is no need for this, as the box has built-in steam holes. You do not need to remove the strap either.
The strap is made from silicone, which is a very durable material, that retains both its colour and elasticity. The strap is just as robust as the box, so you can easily put it in the freezer, dishwasher and microwave. The strap is very well attached to the button on the box, and therefore unlikely to get lost.
Yes, but it requires a certain age/size of hand to close it. We recommend it for ages 7 years and up. Box model no. 02 is the easiest to close.
