Bring just the subtlest of color to your bound document with a navy blue Velobind strip. Velobind strips are the most professional and secure binding style available. There are two types available here-hot knife and 4-pin. The hot knife strips will make it impossible for anyone to tamper with your documents, while the 4-pin allows for easy editing. Both offer a clean, minimal look. And they hold the most pages out of any other style-1" holds up to 200 sheets while 3" holds up to 750 sheets of 20lb paper. And we carry our own brand plus GBC's, so they'll work with lots of different machines if need be.
