The Black+Blum Glass Stack + Nest Food Box Set is designed to simplify food storage, meal prep, and meals on the go. Made from premium borosilicate glass, each container is built for everyday durability and can safely move between the freezer, microwave, oven, and dishwasher.

Each food box features a 100% leakproof, airtight lid to help keep food fresher for longer while preventing spills during transport. The integrated lid-lock vent allows you to heat food in the microwave with less splatter, while the semi-transparent lids make it easy to identify contents at a glance. Removable seals also make cleaning quick and hassle-free.

Designed to stack and nest neatly, the containers maximise storage space and are compatible with Black+Blum stainless steel meal prep boxes of the same shape. Available in 380ml, 600ml, 900ml, and 1.2L sizes, they provide a modular solution for storing, transporting, and reheating meals. Independently tested and approved by the experts at The Good Housekeeping Institute, this practical set offers a reliable and more sustainable way to prepare and enjoy food every day.
