GBC ZipBind Spines
These GBC ZipBind spines are professional looking, durable, and have the easiest editing capabilities. What more could you want from a binding style? Plus, these ZipBind are just that much thinner than GBC's ProClick, so turning pages and folding the document over is even easier. They're offered in black in three different sizes. You can order them in packs of 10, 25, or 100 spines. Don't forget to get a zipper tool for your quick and easy editing. And consider stocking up on pre-punched paper and covers, just to make your binding process even easier!
