The cup is made of plastic and it's ~ 500 ml pure. I can only agree with the previous speakers: since I have it, I drink a lot more. The cup is always present on the table. Quite different bottles, which are rather on the ground than on the table.
Lt. Lettering on the ground is suitable for the microwave and dishwasher for the cup. Since the straw above has some play, the hole is obviously not tight. This is also bad because so well drinks can not be filled with carbon dioxide. The straw has a "Rausfall- / pull-out stop", which I find convenient also. So the straw can not veschwinden accidentally. The lid has a separate seal and is screwed with a short walk.
The problem with the sticker I can not understand the way. The sticker is great (it takes up almost the entire height of the cup a) and quite broad. But if you very carefully dissolve it in a corner and then flat pushes away upwards rather than deduct it horizontally, it can be completely detached without residue (without soaking or chemistry).
Conclusion: the second cup will soon be appointed and I can recommend without reservation the cup!
