We discovered that paper towels and current dry erasers in the market do not clean boards as well as the "Footwear fiber fluff." We used the sole of a nike shoe as a base for the eraser and created a thin film adhesive which contained the fluff material. We attached the thin film to the sole base which served as the eraser. When the eraser no longer erases, rather than disposing the entire eraser, the only component tp be replaced is the adhesive film. Our idea is to sell a pack of five adhesive films (which have the fluff on one side). And only sell one base (shoe sole). This idea is both sustainable, profitable, and more efficient than current competitors.
