Bulk Standard Size Mats are perfect for Corporate projects, photographers and artists who print and distribute multiple images, schools and colleges for certificates and many more volume uses. They are value priced - yet are the same quality as our regular Essentials mats with a bright white neutral ph core and backing paper. The pricing is based on volume, selection of only 2 mat colors and fixed opening sizes. All Double mats have a reveal of 3/16". These are MATS ONLY - no bags, backings or tape with these packages. For any custom requirements see our regular priced mats or other packages.
