Includes backer files that can be scored and cut on the laser on poster board using the 80 lb card stock paper Glowforge setting. Great use for scrap busters! Slide them into a self-sealing cellophane bag and you've got a great little add-on product that sells well at markets, bookstores, or as a promo gift.
