In the past, protecting your art from dust and dirt was a time-consuming and cumbersome project. Now, all you have to do is slip your art into these bags, and fold over the flap which has a resealable adhesive strip on it. In just seconds, your art is placed in a safe environment, and can be stored in a storage box, flat file, portfolio, or print rack! These photo storage bags are made of 2 mil polypropylene plastic, and will accept matted or mounted artwork. The size range includes all the traditional and modern sizes including printmaking, drawing, and watercolor sizes. These plastic sleeves for artwork shun the need for shrink wrapping, and acetate film covering, and are far more useful. The art can be removed for viewing, and placed back in the bag and resealed, giving repeated access while keeping out dust and dirt. These photo sleeves have a 1/8" tolerance for the Trading Card Packs, 1/4" tolerance on both sides up to 13x19", and a 1/2" tolerance for sizes 16x20" and larger. These archival polyethylene bags are available in a variety of two pack options: 25 and 250. They are available in 15 different sizes ranging from 2.5x3.5", 4x6", 5x7", 6x8", 8x10", 9x12", 11x14", 16x20, and more.
