Features: 1. Perfect compatibility design: Our sink drain filter has a small diameter and two silicone rings ensuring a perfect fit with various drain holes ranging from 34 mm to 40 mm (1.34 to 1.57") 2. Internal mesh against clogging: Unlike conventional drain plugs with pressure buttons, the upgraded pop-up drain stopper includes an internal mesh that collects hair and prevents it from entering the drain, ensuring your rings never re-enter the drain system again. 3. High-quality and durable material: Our sink drain plugs are made of high-quality, thickened corrosion-resistant stainless steel and brass, offering a smooth, comfortable surface, solid structure, and long-lasting use without cracking or leaking. 4. Easy installation: Tool-free installation, thanks to its simple structure, anyone can install the pop-up drain pipe by removing the old one and inserting the plug into the sink hole to complete the installation. 5. Easy to clean: To clean it, simply remove it, rinse it with water, and reinstall it.
