Sink Strainer, with pop-out stopper, 4.5"" / 11.5cm dia, grey/green, plastic and recycled plastic. Fits most sinks and is more effective than twist-close stoppers. Pops on top of the strainer when you need to fill your sink, and the strainer’s tab makes it easy to remove from the drain, even when the sink is full. Simply invert the basket to empty it, and your fingers never have to touch “the yucky stuff”.
