12-pack Cube Boveda's Cube arrives in a ready-to-go display box of 12 individually wrapped Boveda to be sold as one 12-pack unit or individual packs. Each 67g Boveda is perfect for curing/storing up to 1 pound of flower. Boveda not only knows 2-way humidity control for packages and containers - they invented it. Their patented humidity control packs regulate moisture content, keeping the contents of your containers at the perfect desired level. They don't need any activation or maintenance. Just place them in an airtight container with your items, and Boveda technology will do the rest. Only Boveda responds to any atmospheric humidity conditions inside a container by adding or absorbing moisture as needed to maintain the predetermined relative humidity (RH) level on the pack. Your material will stay fresh, with stable moisture content, delivering a consistently exquisite experience every time. Benefits: Lasts 2-4 months depending on conditions. Replace when Boveda turns rigid.
