[Function] This product absorbs moisture in humid conditions and releases the absorbed moisture into the air when humidity levels are low, maintaining optimal humidity levels for your music equipment (guitars, basses, ukuleles, amplifiers, etc.). In addition to regulating humidity, it also effectively deodorizes ammonia, acetic acid, and other odors, and is an excellent mold and mildew prevention agent, helping to deodorize and prevent mold inside equipment cases. [Silica Clean] This product uses high-quality silica gel and Silica Clean, manufactured using a special manufacturing process. Unlike conventional deodorizing and humidifying products, its outstanding effectiveness has been proven through experimental data. It also regenerates its function repeatedly in sunlight, making it an eco-friendly product that can be reused. [Regeneration Indicator] The included regeneration indicator lets you see the moisture absorption status at a glance. A blue regeneration indicator indicates normal operation. A light pink or whitish color indicates the product needs to be sun-dried. [Reusability] This product can be restored and reused by drying it in the sun (for at least half a day). * After drying in the sun, be sure to wait about 30 minutes before using. * Do not attach the play sign directly to the instrument.
