I have used them many times in the past but not in the box.
I have used them in travel humidors or in a zip lock bag, with a box in the bag.
They work well for small quantities of cigars.

The box wont stay sealed well enough to keep thems properly humidified.

Duct tape? No? How about duck tape?

Don't use them in boxes. But use them in all my humidors. Good way to maintain humidity levels in less than perfect humis
