Let your imagination take off with Astrobrights Colored Cardstock, in Metallic Assortment. Creative geniuses and novices alike can create dazzling postcards, booklet covers, presentation bindings, and paper crafting. Our metallic cardstock is thick enough to stand up to frequent handling and the rigors of postal machines, yet smooth enough to work with inkjet and laser printers. Plus, it's lignin and acid-free so it won't yellow over time.
