Boveda Humidity Packs turn hard when the moisture has been removed from them. Don`t throw them out! Put them into a plastic container with a brown sugar Terracotta stone that has been sitting in water for 24 hours. Close the lid and in 24 hours the Humidity Pack absorbs the moisture and becomes liquid inside. The pack can now be put into your jar of Bud to keep your rolling stock at optimum humidity!
