Boveda 84%RH 60g Humidity Control Pack Set of 2, Moisture Control for Wooden Instruments Set of 2 (Retail price: 2,480 yen each) High absorption, for high humidity Boveda 84%RH humidity control packs are used especially in environments with high humidity for wooden instruments and instrument cases. For example, when wooden instruments such as acoustic guitars and violins are exposed to high humidity, the wood can expand, causing deformation and damage. The 84% humidity control pack is designed to maintain a constant humidity in such environments and to properly protect the instrument. Boveda 84%RH 2-Way Humidity Control Pack for Wooden Instrument Cases Boveda is the world's most recognized 2-way humidity control agent. The saturated agent, made of pure water and natural salt, is set to the optimal humidity for each product and sold. When drying progresses, it releases only pure moisture through the reverse osmosis membrane inside the bag, and if the humidity is higher than the humidity displayed on the bag, it absorbs moisture from the air, making it an excellent humidity control agent that repeats absorption and release. *Please also read the profile☆ #ThreePiece☆WeekendTimeSaleNowOn♪ 【6-11.12】$$1980
