That sounds like it might be a small version of the Boveda one at the bottom of my previous post. If so, it's a two-way membrane and it's filled with a non-toxic salt based solution. As the moisture is released, it will become thinner and less flexible, eventually becoming hard or feel "crunchy", you can re-charge it by placing it in a small tupperware container with a moistened towel for a few days and it will absorb the humidity from the air in the container and puff back up.
