DESIGNED FOR CORKSCREW TAILS, DOCKED TAILS & SKIN FOLDS The Squishface Nub Brush is designed for the curved, curled, and folded areas that can trap hair, debris, and buildup. Its wide U-shaped silicone design fits around corkscrew tails, stacked tails, docked tails, and wrinkly skin folds to help gently lift trapped hair and debris. Regular cleaning helps reduce odor, scooting, discomfort, and degradation of the skin caused by trapped moisture and buildup.
