Right now at Costco, you can get this Contigo Kids 14 oz Tumblers 3 Pack for Only $18.99! Thanks to the Contigo Spill-Proof Kids Tumbler with Straw, children as young as 3 can easily transition from sippy cups to a big-kid tumbler. No need to worry about messy spills, even if your toddler holds this well-designed, bright tumbler upside down. Our innovative engineers put a leak-proof silicone seal around the straw opening and a spill-proof valve on the inside. For good measure, they added a soft-grip bottom pad to the tumbler to minimize skids and tipping. Rest assured, all materials are 100% BPA-free.
