These eco sink strainers are made with natural wheat straw, so they’re non-toxic and biodegradable, and they won’t rust or scratch your sink. Sink guards keep food and utensils out of the drain by trapping them in the flexible rubber basket, or plug the drain entirely to fill the sink with water. Pull out of the drain and invert the sink basket to empty it into the trash. Durable and easy to clean. 4" Dia. x 1½" H. Set of 2.
