Glass containers with clip-on or press-on lids are a popular way to store leftovers and prepared meals. Glass does not stain or hold on to smells, and many containers can be used in the microwave or oven without the lid; always confirm with the maker’s instructions.
Compare the lid material, which is usually plastic or silicone, the seal design and whether the set nests for storage. See glass vs stainless steel vs silicone for how the materials differ.
