Food Grade Stainless Steel: Fine mesh filter has no rust issues. It is safe to sift ingredients during food preparation and strain foods such as juices, jams and broths for consumption. Fine sieve: It's fine enough to prevent tiny seeds or grain particles from falling out during straining, but not so dense that it clogs and requires extra effort to shake it, and not so loose that everything comes out. The mesh is deep to help prevent spillage when sifting powdery ingredients like powdered sugar, flour, quinoa and cornstarch. Silicone coated handle provides comfortable grip and better control. VERSATILE TWO SIZES: The flour sifter can be mounted on a cup or bowl when making loose leaf tea, filtering French press coffee, or making juices like cocktails, wine, and more. The strainer comes in handy when sifting flour, powdered sugar for baking/cooking,straining pasta, quinoa, rinsing fruit, collecting seeds when juicing limes and lemons. This kitchen strainer nests easily inside each other, and each strainer has a hanging hole on the handle so convenient storage is no problem.
