this is a quite sturdy 200 ml plastic cup ( enough for the type of drinks I like; you should check how many mls your favorite drinks are before buying this cos it may seem small). the design is really nice and clean too. the only reason I'm giving this 4 stars instead of 5 is because I think its price is a bit too much. Considering this is an official product tho, and it comes from Japan, I understand the inflated price. I'd say it was worth it
