The Luminarc Pure Box Active is a set of six rectangular tempered glass containers designed for versatile food storage and transport. Each vessel holds 1220 ml and measures 20.8 x 15.3 x 7.4 cm, providing ample space for meal prep or leftovers. The transparent glass allows you to identify contents at a glance, while the stackable design helps you organize your refrigerator or cupboards efficiently. These containers feature an airtight active lid with a secure click closure and an integrated ventilation valve, which makes them convenient for heating food. Because the tempered glass withstands temperatures from -20°C to +110°C, you can move them safely from the freezer to the microwave. When you are finished, both the glass and the lids are dishwasher safe for easy cleaning.
