Every sheet of Coredinations Cardstock is acid and lignin-free and of 80 lb weight. This Cardstocks has a core color which "core'dinates" with the surface color. You can choose to keep the core color hidden or add your own creative touch by sanding, tearing, antiquing, or embossing by revealing the colored core. Core Essentials Choclate Mocha is a perfect choice for those guy cards or to make a 3D chocolate cake paper craft. The front side of the paper has a canvas texture while the reverse side is smooth.
