Patented products, Double-reinforced, this toy features exceptional shatter resistance and ultra-strong chew resistance. Adopting the production process of wrapping rigid ABS with soft TPR rubber, it is designed with meteorite-shaped molar bumps on the surface. Combined with the internal rigid ABS structure, it can better clean dogs' teeth during chewing.

It helps dogs pass boring time and reduce anxiety.
