The prokeeper 6-piece airtight food storage container set combines high-quality construction with a silicone seal for airtight storage. The set consists of food storage containers constructed to fit specific ingredients for extended freshness and has measurement markings on the side to clearly display its internal contents. It includes a canister for flour, granulated sugar, brown sugar, powdered sugar, and two, versatile "mini" containers. Each container is sized to fit a standard bag of its corresponding ingredient. All prokeeper food storage containers are designed with stainless steel hinges that swing open for no fuss access to fill or measure, an easy-catch latch to secure the lid, and are dishwasher safe for cleaning.
