Luminarc Pure Box Active Square 3.2 Cup
The Pure Box and Pure Box Active glass boxes have a clip-on top, making them completely airtight and practical for taking your lunch to work! For added comfort, Pure Box Active offers a little extra that changes everything. A small valve means that you no longer have to remove the lid to microwave your dishes. The steam escapes easily, your microwave remains completely clean and your food does not dry up.
