Hornady Rapid Dry Dehumidifier Stone Features The Hornady Rapid Dry Dehumidifier Stone is sized specifically to fit into gun cases safes and tool chests where excess moisture can lead to rust and corrosion over time. Its compact 4.8 by 2.6 by 1.1 inch footprint tucks easily alongside firearms without taking up significant storage space. At just 0.3 pounds the stone adds negligible weight to a safe or case while actively working to absorb ambient humidity. Its black finish keeps it discreet inside a gun safe or case alongside other gear. What sets the Rapid Dry Stone apart from disposable silica packets is its ability to be recharged in a standard oven or microwave giving it effectively unlimited use over its lifespan. Once it has absorbed as much moisture as it can hold a short cycle in the oven or microwave drives that moisture back out restoring its absorbing capacity. That reusability makes it a more cost-effective long-term solution than replacing desiccant packets on a regular basis. Gun owners looking to protect firearms from rust in a safe or enclosed case will find this stone a simple reusable safeguard for sale at GrabAGun.
