These days I use Boveda pack and beads ( humidification beads with propylene -glycol) together, and they are working just fine.
But still by the time, the Boveda starts to dry out, so then I re-humidifying it by using distilled water on a paper towel, wrap the boveda pack with it, and I put the whole thing into a zip-bag for 2-3 days.... and it is like a new one again... I do this every 2 months or so..... So other 2 Boveda I bought from Amazon is still in the box :-D
