Super great training cup - consists of 3 parts which are completely fixed and easily cleaned and made together. The silicon wafer is really the kicker - it drips nix - neither when tilted in the pocket. But allows for a simple drink, so that my daughter 16 months has a lot of fun to the cup (have it the way also in the color petrol - just beautiful!) Thank NUk for this ingenious invention - we also asked about it everywhere!
