An eco-friendly version of our popular Protective Closure Bags, Eco Clear Protective Closure Bags beautifully store and protect cards, art prints, crafts, and more while doing their part to keep our planet green. While ideal for a set of 8-10, 4 Baronial or A1 size cards and envelopes, GC4B2PC measures 4 1/4" x 5 3/8" and can hold a variety of items from cards and stickers to food items and cosmetic products. These bags are made from 1.6 mil, food safe, high clarity, plant-based PLA (Polylactic Acid) material. The reusable adhesive strip is located on the body of the bag to ensure it does not come in contact with your product while keeping it enclosed and protected.
