【High Quality Material】The combination of noble chrome-plated brass and high-quality ABS hard plastic creates a perfect rust-proof sink drain plug for your Ø 40 mm drain pipe. It is odorless, corrosion resistant, wear resistant, not easily deformed and can be used for a long time. 【Effortless】The sink drain cover can be adjusted to the depth of the drain pipe by hand and fixed firmly with a nut. No annoying hair and dirt get stuck in the hair filter - the dirt will flow right where it belongs should be, i.e. down the drain. 【Rubber Ring Design】The sealing ring of the drain plug is made of rubber, which can be closed securely, so that your sink can store water safely without worrying about leaks of water. Thanks to long side rails of the wings of the sanitary sink stopper, it can be perfectly held in place and will not shake. 【Easy Installation】Our flush plug is simple in structure and easy to install. You just need to remove the old flush plug after confirming the size and replace it
