re: Desktop Humidor

For the humidors I sell, I advise wading up a damp paper towel for breaking in for a week or so. 
Fun thing about the Bovedas is you can have a tupperware container with some water in the bottom and recharge a pack or two by leaving it suspended inside, above the water of course.
Around here, one will dry out and before it develops "chunks", I can fatten it back up and reuse for many cycles.
