This True Living Mesh Strainer is 2 1/2 inches in diameter, so it fits neatly over a cup or small bowl for straining seeds from citrus or draining canned goods. The mesh is stainless steel, and the frame is sturdy plastic that's designed to fit onto a cup or bowl for hands-free use. Not just for straining, it's also great for sifting powdered sugar or cocoa powder onto desserts or sifting small amounts of other dry ingredients for cooking and baking.
