Is a Boveda Humidor Bag airtight?
Yes. Think of it as a less bulky tupperdor. The Boveda Humidor Bag is an airtight humidor that prevents moisture from getting in or out. Its strong seal and heavy-duty polymer construction make it 2x more effective for storing cigars than an ordinary food storage bag.
BONUS: A laminated odor-barrier also keeps bad smells out and that good tobacco aroma in. So your smokes won’t end of smelling like the inside of a golf bag and vice versa.
