BPA and ECO-FRIENDLY MATERIALS Silicone - Soft silicone brush, never burn your pet’s paw. CLEAN SAFETY TOOL - Soft and effective silicone bristles, help remove dirt and mud from your dog’s paw and do not injure your pet’s paws in the process. SIMPLE AND EASY TO USE: easy to disassemble and clean. Just rinse and keep on hand for the next muddy encounter. HOW TO USE: Stick the pet’s paws in the pet washer (one at a time), shake the water around or twist the bowl to hook the bristles, and then remove the pet’s paw.
