Kelso 3 Piece Tumbler Set

Let's keep it simple: these Sea Shells tumblers don't leak. The silicone sipper spout design has a built-in valve that stops water from flowing when no one is drinking: it's easy for children to quench their thirst, but won't make a mess if the tumbler is tipped over. It's the perfect choice for active kids, or young ones just graduating from sippy cups who aren't ready for an open-topped tumbler yet. Two tumblers and a bonus sipper are included in the set—the 12-ounce stainless steel tumbler has vacuum insulation, which keeps drinks cold and eliminates water rings from condensation, and the 15-ounce plastic tumbler is lightweight and easy to carry. They're both durable, reusable, and completely BPA free.
