D'addario Vitalizer Refill Pack - 72% Humidity

This is the replacement humidity control pack which is to be used with the D'Addario Woodwinds Reed Case that fits 8 reeds.

Regular replacing of the humidity pack is necessary as the old packs can dry up and cease to moderate the humidity. We recommend replacing the pack every 3-4 months or so. It is now only available in the standard 72 per cent humidity pack.
