Definitely recommend
I’m really pleased with the quality and quantity for the price! This has been super helpful in my homeschool classroom as I opt for printing my children’s curriculum and binding them myself!

Color of spirals not as shown.
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.

I’m very happy with this pack of spiral binding coils. It comes with 100 coils in 4 different sizes, which makes it really versatile for different projects. They’re standard binding coils, easy to use, and a great value for the quantity and variety. Exactly what I needed.
