Silica gel is enclosed within a compact aluminum canister designed for placement inside the Croxs case, offering protection for cameras or computer equipment against moisture. The eco-friendly design allows for rejuvenation by placing it in an oven at approximately 120 degrees Celsius for about 3 hours. When the indicator window turns green, the silica gel is ready to be used anew. This is particularly beneficial for your Croxs case when traveling to various locations where moisture is a potential issue.
