Make meal prep fun! The Ello Duraglass 4-piece Meal Prep Set includes two 3.4 cup (27oz) glass containers each with leak-proof lids and silicone protection boots to protect from chips and breaks. Duraglass containers are dishwasher, microwave, and oven safe without the lid. No need to remove the silicone sleeve! Our non-porous glass ensures that it won't absorb stains or odors, keeping your food fresh and your containers looking new. Please remember to let containers cool before placing them on wet or cold surfaces.
