The Progressive Prepworks ProKeeper 6-Piece Bakers Storage Set is a stackable food storage system designed to keep baking essentials fresh and organized. The set includes six airtight containers, each with its own specialized integrated tool: a Flour Keeper (4.6 qt, holds up to 5 lbs) with a removable leveling bar, a Sugar Keeper (2.3 qt, holds up to 4 lbs) with a flip-open pour spout for one-handed use, a Brown Sugar Keeper (1.8 qt, holds up to 2 lbs) with a terra cotta disk that keeps brown sugar moist, a Powdered Sugar Keeper (1.3 qt, holds up to 1 lb) with a removable leveler and duster, a Coffee Keeper (1.8 qt, holds about 1 lb) with UV-blocking tinted plastic and a 1 tablespoon scoop, and a Mini Keeper (1.5 cup capacity) with a removable leveler and sliding shaker screen that fits a standard box of baking soda.

All containers feature easy-catch lids with silicone seals for airtight storage, and measurement markings on the sides for quick reference of remaining contents. The set is designed to accommodate standard grocery store-sized bags of baking ingredients. All containers are BPA free and dishwasher safe, with the exception of the Coffee Keeper (top-rack only) and the terra cotta disk (hand-wash only). To use the terra cotta disk, soak it in water for 15 minutes, blot dry, snap onto the lid, and re-soak every 3 months to maintain moisture.
