People usually clean their glasses with any type of cloth, frequently with their shirts, which ends up scratching and damaging their glasses. BBDO Mexico and Scotch-found a cool way to prevent this. They produced the 'cleaning t-shirt' designed with a Scotch-Brite Microfiber in it, so people could clean their glasses without scratching them anymore. The t-shirt was availabe in any 3M store to give away as a gift.
