The OXO Good Grips sink strainer combines sleek stainless steel with flexible, stain-resistant silicone. The easy-to-clean silicone basket traps food debris to prevent clogs. When it's time to empty your strainer, simply pick it up by the center post and invert the silicone basket for easy debris removal. A silicone underside won't scratch the sink basin. Dishwasher safe.
