Create an impressive presentation with these colorful binding spines. Color coil adds energy to your reports and proposals, and demands attention. This spine always keeps its shape with bounce-back flexibility. It lets pages lie flat with 360° rotation for convenient note taking and photocopying. And, it permanently binds, so you can be sure documents stay organized.
