These 8 Piece Nesting sets are vacuum sealed with locking lids that are designed to help save your food and keep them fresher longer. I have saved some money being able to store leftovers, along with even bagged salads longer. I do not usually tend to buy them much, but hey when they are on sale, I can't stop myself. ;)
They are great fitting in the fridge or shelves as storage. And even on the go if you need. I love how easy they are to close, along with staying closed tightly. The hubby even had a hard time trying to open them at first. :P The small button at the top lets you know when they are sealed and keeping your foods fresh.
