Munchkin Miracle Stainless Steel 360⁰ Sippy Cup 10 Oz.

 Munchkin’s Miracle Stainless Steel 360⁰ Sippy Cup utilizes a double wall design to keep drinks cool for 15 hours (plus, it won’t sweat or get hands cold). The dentist-recommended spoutless 360° degree edge allows drinking from anywhere around the rim, like a regular cup, to help support normal muscle development in a child’s mouth. The completely spill-proof, lip activated valve automatically seals when child stops drinking.
The cup is easy to clean with no extra valves or parts.
