Gummed Pad offers an excellent way to make sketches, layouts and notes and keep track of your work until you're ready to file it in your three-ring folder or binder. It contains 50 sheets of smooth, white, 15 lb. paper that is graph-ruled with 4 squares per inch. Sheets are glued along the top 8-1/2" edge and three-hole punched to fit in standard, three-ring binders. The 34 point chipboard backs add stability.
