These durable, leak-proof and stain-resistant containers are the perfect size for any task, from meal prep to leftover storage to takeout. They are uniquely stackable and storable food containers that make the best use of space in the fridge or pantry the lids stack neatly on top of each other and the containers nest inside each other to prevent clutter. The lids are universal and fit any container, so you don't have to search for the right lid. (Except for our 5-ounce containers, these lids are smaller.) These containers feature soft-grip twist-on lids, making them easy to open and keeping food intact. The gasket in the lid provides a leak-proof seal.

These durable containers are stain and deformation resistant so they last a long time. The containers are dishwasher safe, but the seal in the lid must be removed for thorough cleaning.
