【Universal Size】 The sink drain stopper fits drain holes with an inner diameter of 34mm to 40mm / 1.34 to 1.57 inches and can be used for various types of drains. The included silicone ring allows you to adjust the size of the sink stopper for a better fit in the drain hole. It fits most sink sizes, including kitchen sinks, bathroom sinks, bathtubs, and more. (Please confirm your drain hole size before purchasing.) 【Pop-Up Drain Valve】 Improved Pop-Up Drain Plug. Simply press the top cover to switch between storage and deflation modes; it won't pop open when you press the button.

Additionally, all parts of the new sink drain plug can be disassembled for cleaning. 【High-Quality Material】 The universal sink drain plug is made of high-quality thickened ABS and an electrolytic brass core, which is durable, not easy to rust, and has a solid structure that will not crack or leak with long-term use.【Easy to Install】Pack of 2, no tools required, plug and play, quick and easy installation. Simply remove the old sink drain plug and insert the new sink drain plug to complete the installation and use normally. In addition to the plug itself with washers, one large washer is also included.
