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.
