Excellent material The white sink drain without overflow is made of high-quality brass, ensuring durability, resistance to rust, and lead-free composition for safe and environmentally friendly use. The polished chrome finish provides anti-corrosion protection and maintains a long-lasting shine in the bathroom. Ceramic waste without overflow The drain valve features a unique ceramic cover that resists scratches and offers a better fit for ceramic basins compared to standard wastes. Designed without an overflow hole—please confirm your basin does not have an overflow hole before purchasing. Double joint construction The drain assembly includes three high-quality silicone gaskets to create a double seal. This design enhances durability, prevents drying, improves sealing performance, and helps prevent water leakage. Minimalist design The sink drain valve is built with a solid brass compression spring for reliable rebound and quick sealing. Simply press with your fingers to instantly open or close the sink plug. Easy installation The click-clack sink plug has a standard 1-inch connection and can be installed in a few simple steps using a wrench. Suitable for most sinks or basins without an overflow hole. (Tip: Ensure the seal is correctly positioned to avoid leaks.) Note: All measurements are manually taken. Please allow 1–3 cm variation due to differences in lighting and display screens.
