Binders are 100% recyclable and feature the patent pending EZ Clip ring removal system. Entire ring mechanism easily removes without tools to allow for full recycling of the covers separate from the rings. Attractive, professional looking, case bound binders utilize extra sturdy, warp-resistant chipboard covered with coated, textured paper to resist scuffing and moisture. Slant Angle D-rings are easy to open and load up to 25% more paper capacity than round rings. Reinforced spines for extra long life. Holds 11" x 8-1/2" paper.
