Boveda for Music | Single Fabric Holder for 49% RH 2-Way Humidity Control | For Use with 1 Boveda Size 70 to Protect Smaller Wooden Instruments from Cracking and Warping

HOW IT WORKS: Our patented two-way humidity controlled Boveda packs compensate the atmosphere inside your musical instrument; When water vapor is needed, Boveda releases the cleanest and most purified humidity; When there is too much moisture in your musical instrument, Boveda absorbs the excess; Boveda requires zero maintenance, your instrument will always be protected; Wide fluctuations in humidity will cause the wood to expand or shrink, and degrades its performance abilities

EFFORTLESS PROTECTION: Nearly all guitars and other musical instruments made from wood are built in an environment where humidity is closely controlled and monitored; Wood is susceptible to warping that can alter the tone and timbre of the instrument, or even worse, cause it to crack during the manufacturing process; Protect your instruments against warping, cracks, and other damage cause by lack of humidification

Use with all Boveda, including High-Absorbency Boveda for wooden instruments in high-humidity climates (replacement Boveda available separately)

Soft, like a polishing cloth, so the polyester exterior is safe to store with an instrument
