I ordered these binding spirals for my husband who was needing them to bind a portfolio. The product states that there are 50 total spirals, 10 of each, and colors are listed as red, blue, yellow, green, pink. I chose this specific package for the red spirals, and they were closer to orange than red. Also (not pictured), the blue is more royal than it is navy blue. The spiral on the right of the picture is what came in the package. The spiral on the left is the spiral that I ended up spray painting red. Otherwise, the spirals work great. They are lightweight plastic, easy to use, and the size is just as described. I was able to use these to bind 75 pages, 2 pvc covers, and a cardstock cover. If you need to bind more than this, I would size up as the amount of pages I used was close to maxing out the spirals capacity.

very good quality

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!
