We're a paper company, that's who we are. We provide you the best quality cardstock products in various forms. So when you want to get the best quality card stock in the widest selection of colors, styles, sizes, and textures to choose from, you go to JAM. The difference between cardstock and paper has to do with thickness, or the weight of the material. So when you need something more lightweight, like printing or writing paper, look through our paper choices. If you need something a little thicker, get our cardstock paper in your shopping bag.
