Musical Instrument Humidity Control Sheet, Made In Japan. Maintains Optimal Humidity of 40-60%. Suitable for Guitars, Ukuleles, Violins, and Wind

[Function] This product absorbs moisture when humidity is high and releases the absorbed moisture into the air when humidity is low, maintaining optimal humidity at all times and improving the condition of musical equipment (guitars, basses, ukuleles, amplifiers, etc.). In addition to humidity control, it also has a high deodorizing effect against ammonia and acetic acid, and is excellent at preventing mold, so it is useful for deodorizing and preventing mold inside equipment cases. [SilicaClean] This product uses high-quality silica gel and SilicaClean, which is manufactured using a special process. Unlike conventional deodorizing and dehumidifying products, its outstanding effect has been proven by experimental data. In addition, it is an eco-friendly product that can be reused many times as its function is regenerated by sunlight. [Regeneration Indicator] A regeneration indicator is included so you can see the moisture absorption status at a glance. When the regeneration indicator is blue, it is in the normal state. When the regeneration sensor turns light pink or whitish, it is a sign that it needs to be sun-dried. [Reuse] This product can be reused by drying it in the sun (for half a day or more) to restore its function. *After sun-drying, please wait at least 30 minutes before use. *Do not attach the "Restoration" sign directly to the instrument.
