Leifheit's Fresh and Easy storage containers are now available in square design. These crystal-clear containers are not only pretty but highly functional. The patented one-hand locking technology creates an air and watertight seal to hinder spoilage and keep food fresh longer. Dry goods remain fresh longer and retain their aroma. All containers are sturdy, reusable and stackable in addition to being easy to open. Assortment of sizes are available for different quantities of food and other items. The clear containers allow visual inventory of stored food or other items and the wide opening makes filling and dispensing easier. But don't limit their use to the kitchen. Perfect for office, sewing room, small toys and so much more. Made from SAN plastic which is both shatterproof and resistant to stains and odors. These containers are BPA free, and dishwasher safe but please hand wipe the lid. 1-quart/34-ounce capacity and 3 year warranty.
