Airtight High Borosilicate Glass Microwaveable Food Container & Lunch Box

Prepare, store, reheat and serve meals in one versatile glass container. Made from high-borosilicate glass, this lunch box offers a clear view of its contents while resisting everyday temperature changes. Choose the compact 640ml undivided version for snacks, sides and lighter meals, or the larger 1040ml version with a fixed glass divider for balanced portions.

Four locking clips and a removable silicone sealing ring create a secure closure to help keep saucy meals contained during storage and transport. The tempered-glass lid includes a flip-up air vent: keep it closed while carrying the lunch box, then open it before microwaving.

Flat lids allow containers of the same size to stack neatly in the refrigerator, helping you organise meal-prep portions without taking up unnecessary space. The ivory locking frame gives the container a clean, understated finish suitable for home, school or work.
