The design and color complement your work environment and let you organize by spine color. Flexible, PVC-free, nonstick poly material prevents ink and toner transfer. Spine-mounted, metal round rings accommodate letter-size documents. 1" ring capacity holds up approximately 175 sheets. Lightweight, stylish, durable binder also features exposed rivets.
