The Lock & Lock Boxes have the same quality as the legendary Tupperware, but at a fraction of the Tupper Award. That it goes anderst, Lock & Lock shows. The cans are perfectly finished, close absolutely tight from and prevent by its strap perfectly accidental opening when, for example, has a box on the go in your pocket. This is a clear advantage to Tupperware! In addition, the plastic is just as high quality as the Tupperware, the doses are dishwasher safe, freezer suitable, usable in the microwave (just to heat, do not boil!) And let each other or stacked into each other. The Lock & Lock tins can recommend in all respects.
