The OXO Good Grips 2-in-1 Sink Strainer & Stopper effectively trap food scraps while washing dishes, and quickly and easily transforms into a stopper to fill the sink up for soaking. The durable silicone basket prevents clogging, plus it flips inside out for emptying and is easy to clean. A simple twist of the knob switches you back and forth between straining and stopping. The stainless steel exterior is stain resistant, while the soft silicone underside protects sink surfaces. BPA and PVC free. Dishwasher safe.
