High Quality MaterialThe combination of noble chrome-plated brass and high-quality ABS hard plastic creates a perfect rust-proof sink drain plug for your 40 mm drain pipe. It is odorless, corrosion-resistant, wear-resistant, not easily deformed, and can be used for a long time. EffortlessThe sink drain cover can be adjusted to the depth of the drain pipe by hand and secured firmly with a nut. No annoying hairs and dirt get stuck in the hair filter - the dirt will flow where it should be, i.e. into 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 safely store water without worrying about water leakage. Thanks to the long side rails of the wings of the sanitary sink stopper, it can be perfectly held in place and will not shake.
