Clearly showed whether my desiccant packets were working.
These worked great. I was staying in Hawaii and put these inside things like the box for my sewing machine, along with desiccant packets. I also left one out as a control. The one I left out showed about 90% humidity and the one in with the sewing machine showed about 30% humidity.
