Meet Ouch Mouse.
The soft plush Mouse is designed to wrap around the sides of the frozen 1-1/4 x 1-1/4 x 1-1/4" Boo-cube providing softness and comfort while gently applying diffused cold to the Owie. The set includes one ouch Mouse and one Boo-Cube. Boo-cubes are 100% bisphenol-free plastic and arrive pre-filled with distilled water; simply pop the Boo-Cube in the fridge or freezer until it's needed. Plus, ouch Mouse is machine washable!
