HIGH-QUALITY MATERIALS: Our pop-up sink plugs are mainly made of high-quality stainless steel and brass, with high finish, anti-corrosion, anti-rust, anti-cracking, and one-piece molding. Good resilience, one press can quickly seal drainage and storage BUILT-IN FILTER: Different from ordinary button drain pipes, there is an anti-clogging basket inside the bullet core copper plug, which can collect hair and prevent the drain pipe from clogging. For example, jewelry, rings, dirt, etc. will not be sucked into the drain pipe EASY TO INSTALL: No tools are needed, you only need to take out the old sink plug and install a new universal stainless steel drain filter, suitable for washbasins, sinks, kitchens and bathrooms DUAL MODE SWITCHING: The pop-up design of the no overflow pop up sink stopper subverts the inconvenient drainage method. Press the top cover to switch between 2 modes, water storage and drainage, and can be taken out for cleaning at any time SATISFACTION GUARANTEE: Risk free purchase. If theres any quality problem, we will arrange the replacement (new Stainless Steel Drain Filter) for you or refund. We will offer the best solution for you when you write to us
