Easy to install and remove, enhancing convenience in daily use. Features a pop-up valve that helps prevent sewer odors by sealing the drain pipe. The plug remains stable when pressed and does not tip over, ensuring reliable sealing and easy emptying. Equipped with two black silicone seals to enhance stability and leak resistance. Built-in anti-clogging basket filter effectively catches debris and prevents small items such as jewelry, rings, and dirt from entering the drain pipe, reducing the risk of clogs.
