Simplify your bathroom sink with this 3-in-1 pop-up drain strainer, merging water storage, fast drainage, and anti-clogging functions—plus anti-odor protection—into one sleek unit. Equipped with 3 O-rings, it fits 99% of standard US sinks (1.06"–1.61" inner diameter, ≥2.2" depth). Scientifically designed holes enable quick water flow while trapping hair, jewelry, and debris, and its brass bounce core with double rings ensures anti-leakage performance. Crafted from rust-proof brass and stainless steel, it installs by direct insertion; press once to store water, again to drain. Eco-friendly (reduces chemical cleaners) and easy to clean—simply split, wipe, and rinse.
