Boveda Humidity Packs?

[geep]

I use those in my travel humi's. They work well. I'ved used the same ones for years. You can recharge them. When one starts to dry out I swap it out for one in the cooler. By the time I need another, the old one is recharged. I've worn out the paper on the package before ever wearing out the humi stuff.

any secrets on recharging the Broveda Packs, I have an auto ship with them but it would be nice to know just in case
