These Address refill pages are 6-hole-punched and designed to fit compact system binders like the Raymay Davinci System Binder (Bible/Personal Size). The pleasant, cream-colored sheets are thin to reduce bulk, yet durable and resistant to bleed-through. Because address sheets tend to be flipped back and forth often, they are made of Yupo synthetic paper. This type of paper is exceptionally smooth to the touch, and is water-resistant and tear-resistant. This pack contains 10 sheets, with each sheet including 16 address spaces (8 address spaces on each side).
