Make meal prep fun! The Ello Color Lock 10-piece Meal Prep Set includes (5) 3.4 cup glass containers each with leak-proof lids. BPA-Free plastic lids feature air tight snaps that won't leak and keep food fresher longer. Containers are dishwasher safe, and microwave and oven safe without the lids. Our glass is non-porous, so it won't absorb food odors, flavors, or stains. Do not place hot containers on wet or cold surfaces.
