Stack + Nest is here. Glass food containers that do it all. Four sizes, stacking and nesting into a fraction of the space. Same iconic lid design as our stainless steel meal prep boxes, and fit together with them seamlessly when not in use. Oven, microwave, air fryer, freezer and dishwasher safe. Airtight seal for fresher food. Don't just take our word for it, the Stack + Nest range comes tested and approved by the Good Housekeeping Institute.
