Query: Storage Box 15.3x30x16 Airtight

This container is airtight. Which makes it perfect for what I need it for, a humidor for cigars. Made of plastic, not the flimsy type of plastic, but of a more hefty type. The lid has locks and a seal all around the edges. This container so far has worked fine, and looking to get another one soon.
