My daughter doesn't have the biggest appetite but loves to have a class of milk with lunch - and this handy container has made it easy to do this on schools days too. So far we've had no leaks. I only ever wash it by hand, and find it is quite easy to wash and keep clean. I'm glad I bought two!
Just bought 2 small drink in the box for a 1 year old she loves them no spill, hard wearing, compact and she nows looks for the bright coloured box to get a drink of water recommend to buy
