[Sink Drain Plug] The water drain design improves traditional drainage methods. Simply press the top cover to switch between plug (water storage) and filtration (drainage) modes. [Built-in Filter] This drain features an anti-clogging basket filter that collects hair and prevents blockages in drain pipes. [Tough Material] The drain stopper is made of thickened stainless steel, which is crack-resistant, smooth to the touch, rust-proof, corrosion-resistant, and anti-discoloration. [Easy to Install] Anyone can install this drain filter due to its simple structure and tool-free setup. Remove the old sink drain plug and insert the new core.
