Tupperware products are great food storage containers. They have stood the test of time, I remember mum use to come back from Tupperware parties loaded with them. She still has some of them till this very day, and if the seal gets chipped or crack, just replace it with a new one - you know it has a Lifetime Guarantee on most of its product range.
