Four replacement packets for the Boveda humidifier system.

The Boveda system automatically protects your instrument against warping, shrinking, cracks and other potential damage caused by lack of humidification or too much humidification. It does so seamlessly without refilling or wetting sponges, snakes or discs. Simply place a Boveda packet in your case and close it. Boveda does the rest, keeping your instrument at a constant relative humidity between 40-50% while your case remains closed...giving your instrument the ideal climate.

This package includes four packets.
