These note-cubes are made from 120g, "Color Vellum" papers. The stack of multi-colored sheets are gummed on one side for efficient storage and are designed to allow removal of one sheet without breaking the "block". The cubes coordinate with all of the many Color Vellum products. In two sizes: 2"x2" (312p) and 3.1"x3.1"(480p). Made in Belgium. Imported by OrangeArt.
