Make meal prep fun! The Ello DuraGlass 10-piece Round Meal Prep Set includes (5) 3.4 cup glass containers each with leak-proof lids and extra thick silicone protection sleeve to protect from chips and breaks. Crystal-clear BPA-Free Eastman Tritan plastic lids let you see contents inside and include air tight snaps that won't leak and keep food fresher longer. Containers are dishwasher safe, and microwave and oven safe without the lid and no need to remove the silicone sleeve! Duraglass is non-porous, so it won't absorb food odors, flavors, or stains. Do not place hot containers on wet or cold surfaces.
