【Durable】 The drain stopper 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 hold hair and food debris. 【Stable】 Each filter has four suction cup bases, ensuring a stable and secure fit that is not easily moved. The drainage holes in the drain cover are clean and well-placed, allowing for very fast drainage. The drain cover measures 13.8 * 13.8 cm / 5.4 * 5.4 inches, so it can only be used on drains smaller than this size. 【Easy to Clean and Install】 This silicone suction cup filter for the sink is easy to clean with warm soapy water. However, it only works on smooth tile or glass surfaces and is not suitable for matte or uneven surfaces. 【Area of Use】 Suitable for all standard drain types, it can be used in bathtubs and kitchen drains. It easily catches food debris, hair, and other waste during drainage, as well as any residue you want to prevent and catch for smoother drainage. 【Customer Service】 If you have any questions, please feel free to contact us.
