Our ever convenient 10 glass container food storage set with lids is microwave, preheated oven (not lids), refrigerator, freezer and dishwasher safe. The handy plastic lids let you cover any leftovers airtight and easily store them in the refrigerator for later. Lids are top-rack dishwasher safe. This set is great for college students, new homeowners and gift registries, too.
