GBC knows binding! These revolutionary new binding supplies from GBC simply zip closed and then zip open for the quickest and easiest editing. They work with the plastic comb binding 19 hole pattern. And we also now feature the new style of black GBC ZipBind spines which are thinner and allow for easier page movement. We carry and offer 25, 50, and 100 packs of ZipBind supplies. Use these supplies along with your plastic comb binding machine or with pre-punched paper and binding covers, if you need to speed up the process. And we even offer a kit that has everything all prepared for you! Get binding with GBC today!
