I used to sell tons of these at craft shows. They are used as air fresheners and actually work pretty darn good. You sit on a plate and every few weeks or so you hit with a blowdryer which melts the wax a little bit then brings the smell back to it's original strength. The big thing now is dipped toilet paper, paper towels, etc. I have a roll of toilet paper over a year old that still smells AMAZING!
