Multi-Functional 3-in-1 Integrated Design: This kitchen sink drain strainer combines food filter basket, water storage stopper and anti-overflow structure all in one piece. It can filter food scraps, hold standing water for dish washing and block sewer odors, replacing separate drain accessories to simplify your sink setup. Anti-Clogging Filter Basket Captures Debris Efficiently: Dense evenly spaced mesh holes trap vegetable scraps, rice residues, food crumbs and tiny leftovers before they flow into pipes. It stops pipeline blockages effectively, and the removable basket lets you dump waste in seconds without messy pipe cleaning. Rust-Proof Thick Stainless Steel Construction: Crafted from sturdy solid stainless steel with polished anti-corrosion finish. It stands up to long-term touch with dish soap, hot water and food leavings, won’t rust, deform or stain for years of daily kitchen use. Tight Sealing Stopper Blocks Odor & Water Leakage: Built-in soft sealing ring creates a fully watertight fit when closed. It locks water inside the sink for soaking tableware while keeping unpleasant sewer gas away from drifting up into your kitchen space. Universal Fit & Effortless Daily Maintenance: Standard size fits most common household kitchen sink drain openings. All detachable parts can be rinsed directly under running water; no hidden gaps trap grime, making daily cleanup quick and hassle-free.
