Make Your Selection: Lock & Lock 5-piece Airlock Rectangle Storage System

Keeping track of leftovers and other perishable foods is even easier with this smart storage system. Each piece features the patented four-hinge seal for easy placement and removal. But what really makes them stand apart from other plastic containers is the dial in the lid. You can use the dial to identify the date that food was first put into the vessel. Or the date by which it should be consumed. From Lock & Lock.
