Rehumidifying Bovida packs? (seems to be working...)

I've been doing this for a while now. I have some boxes that won't fit in the vino, so I se Boveda packs in them. When they start to dry up I just swap them out and rehydrate them. I keep telling my brother to bring back the larger packs I send him with for his desktop so I can recharge them, but he always forgets.
