Surprised to see someone advertising an illegal use for a product. Bet there is some fine print somewhere about using this product. It is an old trick gone modern. Folks have been hiding sanding products in their towels for a long time. Just be carefull about using, someone may "physically object".
An old trick....Spray a spot on your towel with contact cement, sprinkle it with anything abrasive, works pretty good. Less noticeable.
