“Kev Koala is delightful! My 6 month old quickly got the hang of using the straw. It has a clever and fun design where you pivot back part of the lid to expose the straw. Once the lid is closed, water cannot leak out of the straw, so I can pop Kev Koala in my bag without any worries. If my baby tips the cup upside down whilst the straw is still exposed, the only small amount of water that can leak out is that which has already been sucked up into the straw beforehand. So never any big spills.”
