They're 100% recyclable, great in the dishwasher, and microwave-friendly so no more heating up your child's food in a ceramic dish, only to transfer it to a plastic one. And, of course, there are no concerns about BPA or other chemical leaching. Finally, they have a great retro, no-nonsense design.
So get back to basics. Give your child a glass that's actually a glass. Try Kidishes. The clear and simple alternative to plastic.
