D’addario Reed Vitalizer refill

Refill for your D'addario Humidity controler reed case.  This refill needs to be changed every 45 to 90 days.

The Reed Vitalizer Auto HCS packet consists of a formulated salt, water, and gel solution contained in a leak-proof, watervapor-permeable membrane. Based on scientific principles, the saturated solution of salt in water will maintain a constant auto-level of relative humidity within a sealed environment (your reed case) ensuring ultimate reed consistency. The Reed Vitalizer Auto HCS membrane ensures purity and allows for super-fast water-vapor transmission. The membrane acts much like the filtration used in water purification systems by inhibiting the passage of soluble substances (like salt) and by allowing only pure water vapor to pass in and out of the membrane. The membrane also allows for a fast rate of water vapor transmission as the solution responds to the changes in the ambient environment.

73% is the medium-level Humidity Control Pack. Eliminates placing reeds in water and requires minimal wetting. Simply moisten reeds in your mouth and they will be ready for normal use.
