Durable: The drain plug is made of high-quality silicone, which resists rust, corrosion, and limescale. It is soft, lightweight, and not easily deformed. The sink is large enough to contain hair and food waste. Stable: Each filter has 4 suction cup bases and can stick securely, making it not easy to move. The drainage holes in the drain cover are clean and dense, allowing for fast drainage. The size of the drain cover is 14x14cm / 5.5x5.5in, so it can only be used on drains smaller than this size. Easy to Clean and Install: Suction cup silica gel sink strainer; simply wash with warm soapy water for easy cleaning. It works only on smooth tile or glass surfaces, not suitable for matte or uneven surfaces. Range of Application: Suitable for all common drain types, can be used in bathtubs and kitchen drains. It easily catches food residue, hair, and other debris during draining, as well as any residue you wish to prevent and collect for smoother drainage.
