Boveda Humidity Packs for Musical Instruments – 4 Pack, Standard Size, 49% RH Two-Way Control

Boveda Humidity Packs for Musical Instruments – 4 Pack, Standard Size, 49% RH Two-Way Control

Product Description

These Boveda packs maintain stable humidity in instrument cases to help prevent warping and cracking of wooden instruments. The 49% relative humidity target sits within an ideal range of 45–55% RH and uses a two-way mechanism: if the air is too damp, moisture is absorbed; if it is too dry, water vapour is released. Each pack is designed for storage in a protective Fabric Holder and should be replaced every three months. This 4-pack comes in a resealable bag for convenient storage, with no daily maintenance required. Suitable for acoustic and electric guitars, woodwinds, and bowed instruments, the packs are intended to protect instrument condition and performance by stabilising humidity within cases.
