Durable: The drain stopper is made of high-quality silicone that resists rust, corrosion, and limescale buildup. It is flexible, lightweight, and won't easily deform. The sink is large enough to hold hair and food scraps. Stable: Each strainer has four suction cup bases that snap securely into place and won't easily shift. The drainage holes in the drain cover are clean and dense, ensuring very fast drainage. The drain cover measures 14 x 14 cm / 5.5 x 5.5 inches, so it can only be used on drains of this size. Easy to Clean and Install: The silicone suction cup sink strainer should be cleaned with warm, soapy water. It is very easy to clean but is only suitable for smooth tile or glass surfaces, not matte or uneven surfaces. Applications: Suitable for all common types of drains, can be used for bathroom and kitchen drains, easily intercepts food scraps, hair and other debris from drains, and any debris you wish to prevent and capture for smoother flow.
