About this item
  • Dual Action Humidity Regulation: The 49% RH (relative humidity) humidity regulation pack automatically releases moisture when the air is too dry and absorbs excess moisture when it's too humid. This maintains an ideal humidity range of 45–55% RH in your instrument case. A balanced environment helps protect wooden instruments from damage caused by moisture fluctuations, such as warping, cracking, or other structural issues.
  • Safe Materials: Crafted from natural wood pulp and cotton, the pack is free of preservatives and fully biodegradable. Unlike other materials, it doesn’t produce heat, dissolve, or emit odors when exposed to moisture, ensuring safety for both your instrument and the environment.These features extend your instrument's lifespan and stability, keeping it in optimal condition.
  • Simple Setup: Remove the external foil packaging without opening the humidity pack. For guitar cases, place one sealed pack on the headstock and another on the soundhole. For guitar bags, place one sealed pack on the soundhole. Close the case or bag, and the pack will regulate humidity automatically, protecting your instrument from harmful fluctuations.
  • Precise Monitoring with a Hygrometer: For optimal performance, use it with a hygrometer (not included) to monitor humidity levels accurately. Each pack can remain effective for up to three months, though its lifespan depends on environmental conditions. If your hygrometer shows humidity levels outside the 45%–55% range for more than three days, replace the pack to ensure continued protection.
  • Wide Application: The rayzm 49% RH humidifier/dehumidifier pack is designed for wooden stringed instruments such as guitars, ukuleles, violins, banjos, mandolins, and cellos. It is also suitable for wind instruments like saxophones, clarinets, oboes, and recorders, ensuring reliable protection across various musical instruments.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
