etpu foam, steamed and blasted into shape under serious heat and pressure. floats, bounces unpredictably, doesn't absorb water like rubber does.
is it indestructible? no. nothing is. but it takes a lot more convincing than most balls before it gives up.
material: ETPU foam finish: molded, speckled color pattern sizes: M (2.6 in / 1.1 oz) / L (3.0 in / 1.6 oz) for: dogs 15-121 lb, and cats (supervised play recommended) heads up: bounces unpredictably, floats in water, not indestructible under heavy/sustained chewing
no instructions included. he already knows what to do with a ball that won't stop moving.
