Evenflo Triple-Flo Tumblers are new and improved with a tighter fitting valve
– which means they really don’t leak! The tumblers have a suggested price of just under $2 and are made of BPA-free plastc. You can adjust the flow rate, which is great for using as a starter cup all the way to an in-the-car cup for older kids. The shape fits little hands well, and the most unique part of the design is the lid - it curves in so there's room for little noses when the cup is tipped up. They can be found at Walmart and come in four fun colors.
