【Fits the Drain Hole Diameter】The sink plugs fit the sink drain hole with an inner diameter of 34 mm to 37 mm (1.34 to 1.45 inches). Please check the inner diameter of the sink drain before purchasing. 【Premium Material】The drain strainer plug is made of a plastic rebound core made of stainless steel and brass, effectively resisting scratches, corrosion, and rust. Suitable for sinks, basins, kitchens, and bathrooms. 【Two-Mode Switch】Lightly press the top cap to switch between two modes—the plug (to keep water in) and the strainer (to drain water out). 【Easy to install and clean】Without tools, simply remove the old one and insert the rebound core to complete the installation. All components can be easily removed for easy cleaning. 【Special anti-clogging design】The drain outlet has an anti-clogging basket strainer inside, which can collect hair and prevent the drain from clogging. It also prevents jewelry and rings from falling into the drain.
