【304 Stainless Steel & Pure Copper Core】: This is a newly improved drain plug for washbasins. The lid is made of high-quality stainless steel and is rust-resistant. The strainer uses a net, so cleaning is as simple as quickly replacing the net. There's no need to scrub away slime or remove stubborn tangled hair, making cleaning very easy. 【Solves Washbasin Drain Problems】: Are you troubled by common drain problems like hair clogs, water stains, and odors? This product solves all of those problems! The washbasin hair catcher is removable and securely catches hair, rings, and other small items before they enter the drainpipe. Furthermore, when water is not flowing, the valve at the bottom automatically closes, reliably blocking the backflow of odors and the entry of insects! 【Liberation from Cleaning】: By attaching a net to the hair catcher, it securely catches hair and fine debris in the washbasin. Simply replace the net when cleaning, reducing cleaning work and making the troublesome task of cleaning the drain easier! 【Product Specifications】: Drain plug holder x 1; Fixing part x 1; Leak-proof silicone ring x 2; Hair catcher net x 150 sheets (compatible with drain openings with a diameter of 3.0-4.2 cm). Please confirm that the height of your sink's drain opening is 5cm or more before purchasing.
