Love the variety of colors. They are easy to use. Quality of product surprised me. Not flimsy. Will order again in different size(s) once or if they become available again.

I used this to bind some song pages after punching the pages with my new binding machine. Is pretty sturdy.

Not super sturdy but still a good deal at such a low price.

Beautiful colors! Feels thinner than I'd hoped, but still sturdy enough coiled wire for lightweight binding projects. As intended I suppose though I have yet to use any of them. So happy they came in a box that I can keep them in for storage. Looking forward to making gifts with these. for others and myself of course.

I took apart a large spiral bound textbook and seperated each chapter/lab. I used these coils to put each individual chapter together. I was able to just spin to coils to assemble little books. I used a needle nose wire cutter to bend and secure both edges.
