Compact, easy to store: Small and lightweight with a tail hanging hole and hook design so you can hang it to dry and store it conveniently. Durable core: Stainless steel handle resists bending or deformation during use, providing steady control for scrubbing narrow spaces. Comfortable grip: Ergonomic, nonslip handle gives a secure, comfortable hold for repeated use. Gentle, effective bristles: Fine nylon bristles are soft enough to protect surfaces while cleaning, and are securely attached so they do not fall off easily.

Easy care: Rinse after use and hang by the tail hole to air dry; compact size makes it convenient to keep near sinks or inside cleaning kits.
