Boveda Replacement 49%/70g packets, 12-Pack

Two-way humidity control refills for wooden instruments

Boveda Replacement 49%/70g Packets provide convenient refills for Boveda humidity control systems used with wooden musical instruments. Designed for fretted, bowed, and woodwind instruments, each Size 70 packet provides two-way humidity control, releasing or absorbing moisture as conditions change. The 49% RH formulation helps maintain a more stable environment inside the instrument case without the water, wet sponges, or routine refilling required by traditional one-way humidifiers.

This economical 12-pack is ideal for keeping replacement packets on hand or maintaining Boveda systems for multiple instruments. Each packet measures 5.25″ × 3.5″ and fits compatible Boveda fabric holders, which are available separately and included with Boveda Starter Kits. Simply remove a replacement packet from its individual wrapper, place it in the appropriate holder, and keep the instrument case closed while in use. With twelve individually wrapped packets, unused replacements can remain sealed until they are needed.
