Boveda Small 2-Way Humidification Starter Pack + 4-Pack Refill

Automatic Two-Way Humidity Control for Violins, Violas, and Other Small Wooden Instruments

The Boveda Small 2-Way Humidification Starter Pack + 4-Pack Refill provides convenient, low-maintenance humidity control for violins, violas, mandolins, ukuleles, and other small wooden instruments stored in cases. Designed to help protect sensitive wooden instruments from potentially damaging humidity fluctuations, Boveda's two-way system automatically releases or absorbs moisture as environmental conditions change. The B49 Standard formula helps maintain relative humidity between 40% and 60%, providing a more stable environment without the water or wet sponges required by traditional humidifiers.

This bundle combines the Small Starter Kit with four replacement packets for continued instrument care. The starter kit includes one humidity control packet, a soft fabric holder, and step-by-step instructions. The holder allows water vapor to pass through while providing a protective barrier if the packet is accidentally punctured. Simply place a packet inside the holder, position it in the instrument case where air can circulate, and keep the case closed. With five packets in total, this bundle provides a convenient supply for maintaining humidity control throughout changing seasons.
