Avoid clogging: The sink strainer can effectively prevent clogging of the drain. Each hole is 3mm in diameter which is small enough to hold out hair, food debris, etc., but allow water to pass through. Easy to disassemble and clean: With a stainless steel handle hook, the sink filter is easy to remove and clean. Save cleaning time. Convenient and Simple: Simply place the filter in the corresponding place without any tools. Fits: kitchen sinks, bathtub drains and bathroom drains, etc. Note: Be sure to measure the intended plug hole. Due to product tolerances, there are size variations.
