Just what we need for family photo calendars
Size: 6mm Style: 100P , Black
We make family photo calendars every year and these are perfect for binding them. Our calendars have 15 laminated pages (cover, 12 months, then usually a couple of extra pages for more photos or dates). These coils are very sturdy and a great value!

Easy to use and good quality
Size: Multi Size , 3:1pitch Style: 100P , Black
I have these stored next to my Cinch so when I'm ready to make some notebooks and even flip calendars they'll be ready to use! They are the right size and thickness, the right price, color and quality so I'll be back when I start running low on product.
