Amazon.com Say goodbye to soggy lettuce and vegetables with this Fridgesmart storage container. Tupperwares unique ACE (Atmosphere Controlled Environment) venting system allows just the right amount of air into the container by means of two vents on the end of the box. Flip open one or both vents depending on whats inside--a handy guide gives venting recommendations. For instance broccoli likes a lot of air zucchini very little. Raised ridges on the bottom of the container allow condensation to drain away from produce maintaining freshness. Decorated with a wavy line pattern the textured lid reduces sliding when another container is stacked on top. While the lid creates a tight seal some effort is required to remove it. The container and lid are dishwasher-safe but should not be used in a microwave. This storage container measures 9 by 6 by 3-1/2 inches and like all Tupperware products carries a lifetime warranty against chipping cracking breaking and peeling. --Ann Bieri
