Excellent - good quality- worked well for a program booklet

Great product. Industry standard for this kind of binding.

I am pleasantly surprised by these combs. I do an average of 600 journals each spring and again each fall for various Christian camps. This time I was doing study/prayer journals for a friend's men's group that are thicker than my standard 9mm journals. I was hesitant to order these, as they look very thin in the picture. But, I needed something quickly, so took a chance. They are quite sturdy, go through the roller on the binding machine nicely, and cut perfectly each time. They look good on the books and don't look cheap like other coils I had to purchase in the past in a crunch. I don't use this size very often, but will definitely order again when needed.

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.

These clear and colored spiral coils are an absolute must-have for binding school projects! They are incredibly easy to use and provide a neat, professional finish to all my assignments and presentations. The variety of colors adds a fun, personalized touch, making my projects stand out. The durability of these coils ensures that my documents stay securely bound without any wear and tear. These spiral coils have made my binding tasks a breeze and have added a pop of color to my work. Highly recommend them for any student or teacher looking to elevate their projects!

Perfect for creating Unit pamphlets for my history class

These are strong and thick. Hold their shape and work great. Not like some other flimsy ones being sold.
