【2-Pack Bathroom Sink Stopper & Hair Catcher】 You will receive two units of bathroom sink stopper and hair catcher. This sink strainer/hair catcher (dimensions 5.5 x 5 x 3.3 cm) fits 99% of standard American bathroom sink drains. To ensure proper installation, please refer to the product images before purchasing. Make sure to measure your sink drain hole diameter (must be ≥ 3.8 cm / 1.5 inches) and the depth of the drain pipe (must be ≥ 5.7 cm / 2.24 inches). 【Multifunctional Bathroom Sink Strainer & Hair Catcher】 This upgraded sink strainer and hair catcher has a removable filter basket. Its innovative design cleverly combines a pop-up sink stopper and a sink strainer into a single unit, which is very effective in preventing dirt, hair, jewelry and other debris from clogging the drain pipe. The precisely engineered filtration system ensures unobstructed water flow, giving you a worry-free plumbing experience. Suitable for use in sinks, bathtubs, bathroom sinks and more. 【High Quality and Durable】 The pop-up sink strainer is mainly constructed of high-quality ABS and 304 stainless steel materials, with a glossy metallic finish and reliable rust-resistant properties. Compared with traditional plastic pop-up sink strainers, our bathroom sink strainer has a thickened, sealed and spring-loaded copper core, making it more sturdy and practical. 【Easy Installation and Cleaning】 Installing this bathroom sink strainer is easy: just pull out the old sink stopper, insert the new one, and it is ready to use. The sink stopper and hair catcher have a seamless, integrated design with a high-flow mesh structure that effectively filters debris and prevents clogs, as well as problems caused by insects or rodents. When cleaning is required, simply remove the unit and rinse it under running water; for stubborn residue, a quick wipe with a cloth is sufficient.
