Stainless Steel Material: The bathroom sink stopper is made of stainless steel and brass, which is strong and durable, rust-proof, corrosion-resistant, not easy to break or deform, and has a long service life. In addition, it is detachable and easy to clean, and accumulated residue can be easily removed. Retractable Sink Stoppers: The stainless steel sink stoppers have good elasticity and rebound force. With just a light pressure, water can be quickly sealed and drained. The leak-proof silicone ring closes without gaps, does not backflow, and can prevent odors from the drain. Prevents Clogging: The kitchen sink strainer filters out most solid particles and allows only water to pass through, effectively preventing deposits such as hair, food residue, paper, and other dirt from entering the drain and reducing the occurrence of blockages. Perfect Compatibility: The strainer consists of two gaskets at the top and bottom, which fit perfectly with the sink and keep the sink tidy and clean.
