1. The pop-up drain filter design subverts the traditional inconvenient drainage methods (such as basic plugs with chains). Just press the top cover to switch between the two modes of plug (water storage) and filter (drainage). 2. Built-in filter: Unlike ordinary push-button drains, this drain plug has an anti-clogging basket filter inside, which can neatly collect hair and prevent the drain from clogging. No jewelry, rings, dirt, etc. will enter the drain. 3. Waterproof: It is a thickened, barbed silicone gasket that does not require glue and has anti-oxidation characteristics. 4. Sturdy sink plug: This is an integrated seamless design. The rubber ring around this built-in basket maintains stability and will not tilt when the button is pressed. So you dont have to worry about sealing and drainage. 5. Sturdy material: The pop-up sink drain is made of thickened stainless steel material, which is explosion-proof and crack-proof, sturdy and durable, smooth and comfortable to touch, rust-proof, corrosion-resistant, and discoloration-resistant. 6. Easy to install: Anyone can install the pop-up drain filter because it has a simple structure and does not require any tools. Just take out the old sink drain plug and insert the pop-up core. Features: Material: 1 x Basin Pop-up Drain Strainer Note: 1. Please allow 2-3% error due to manual measurement. Please make sure you do not mind before bidding. 2.
