Who ever similar containers had at home, should know that carbonated fluids may leak. Here happens that by the drink expresses itself through the straw upwards, outside runs back down the straw and then soaked in the beautiful snack Becker snacks. But that is sometimes not a criticism.
Problem is simply that the whole cup is already leaking in. The drink-snack cup must always be transported straight. Add to that the unwieldy size. It is easier to make a water bottle and a small can stow individually in school backpack, instead of this monstrous act 2 in 1 thing, which indeed must stand upright and only irrigates the textbooks in the worst case ...

Insolence of course is the price. For this you get a Tupperware Children water bottle and a box with a lifetime warranty and you can also be sure that these things are free of harmful substances. Example (please Googling, no links can insert here):
EcoEasy Penguin 350ml 8,50 Euro
Sandwich Box 9.90 euros
The child likes of Snacky Magic Cups course, thereof one must not be discussed here. For home ok, go very impractical. Therefore not recommended.
