Εμας τρεχει το νερο απο τον πατο χωρις να φαίνεται να εχει σπάσει ωστε να δω απο που προέρχεται η διαρροη...

It is a bit difficult to open and close. The child needs to bite the straw in order to drink, so if they are not familiar with it, it takes a little time to learn. On the positive side, it keeps the temperature hot or cold for a long time and the materials it is made of are very high quality.

Unfortunately, I have to say that for ages 2-3, it is the worst thing I have bought for one and only reason... They fall and break immediately! Young children easily throw them or drop them from their hands with such force. It's a shame because they are all beautiful and I have bought 4 or 5, I can't remember, and all of them broke quickly due to falling... I recommend them for much older children, obviously kindergarten children.
