Not a conventional moisture-absorbing desiccant, such as silica gel. Emits vapors which adhere to external and internal metal surfaces at the molecular level to protect musical equipment during operation, shipping, or storage. Odorless and leaves no visible residue whatsoever, providing long-term protection against corrosion, even in adverse conditions including salt, moisture, airborne contaminants, and more.
