Boveda Large 2-Way Humidification Starter Kit + 12-Pack Refill

Automatic Two-Way Humidity Control with a Convenient Supply of Replacement Packets

The Boveda Large 2-Way Humidification Starter Kit + 12-Pack Refill provides convenient, low-maintenance humidity control for cellos, double basses, guitars, and other large wooden instruments stored in closed cases. Designed to help protect instruments from potentially damaging humidity fluctuations, Boveda's two-way system automatically releases or absorbs moisture as environmental conditions change. The 49% relative humidity (RH) packets help maintain a stable environment without the water, wet sponges, or frequent refilling associated with traditional humidifiers.

This bundle combines the Large Starter Kit with twelve additional replacement packets for continued instrument care. The starter kit includes three humidity control packets, a double holder, and a single holder, providing everything needed to begin protecting an instrument. Simply place the packets in their protective holders and position them inside the closed instrument case. Replace the packets when they become rigid. With fifteen packets in total, this bundle offers a practical supply for maintaining consistent humidity control throughout changing seasons.
