I've tried other binding spines, but found that the spirals are the easiest to use. They also look good and can be simply unwound if you need to add more pages to your project. I love that MyBinding includes helpful videos so you can see the products in use and get a better idea if the item is right for your needs. I've reached out to customer service when I couldn't find what I was looking for and they were extremely patient and helpful.

Read an article online about how you can use these with a ProClick machine. They work great and this way I don't have to buy another expensive machine. I just use a pair of needle nose pliers to crimp them and it works. It is a bit tedious though.

as ways, My Binding has delivered quality products in a timely manner. We use 5:1 pitch coils - in a odd length. My Binding provides these at a reasonable cost and delivers them quickly. thanks for being so easy to work with and always getting us what we need.

All of the products that I have purchased from My Binding (3.1 wire binding machine, 3.1 binding wire, 3.1 coil wire, which I have used with my binding machine, laminating sheet) are of the highest quality. The quick turn around of my orders are expendent and the pricing is very comfortable. I would highly recommend any products from My Binding, and will be purchasing other items in the near future.

These were too big. I measured my previous coils at 25 mm, but the ones I received seemed much bigger. I cannot use them. I guess with a larger Pitch ratio the mm is bigger? I don't quite understand why that is. Next time I will order a size or 2 smaller. 25mm at 4:1 = 20mm at 3:1 I did not know this. It should be stated somewhere in your instructions or description.
