We have lots of round willow balls that are fun, but how about something more unique... a large willow cube made of natural unpeeled willow. Sturdy for chewing and playing satisfaction. Our bun models, Winnie and Tigger are having great fun destroying the cube. For added interest, we suggest filling the nooks and crannies with hay. Measures 4 x 4 x4 inches (10.16 x 10.16 x 10.16 cm).
