Reusable Silica Clean Guitar Moisture-Controlling Mat, Technard, 28 X 25 X 0.7 Cm

Maintains an optimal humidity level of 40-60%! Simply place it between your guitar and case. This moisture-regulating and deodorizing mat is ideal for preventing cracking and eliminating odors. Using specially formulated silica clean, it absorbs moisture in high humidity and gradually releases it in low humidity. In addition to regulating humidity, it also helps deodorize and prevent mold inside your guitar case. Its functionality can be restored repeatedly by drying it in the sun (with a moisture absorption sensor). Includes a pick pocket (holds approximately 10 regular-sized picks).
