Binditek50 Pack Plastic Spiral Binding Coils, 12mm(1/2"), 90 Sheet Capacity, 4:1 Pitch, Black, 48Loops, for Letter Size, for Students and Coworkers

Delivery better than expected. Have used these coils before, these are one size larger. Same sturdy quality and easy to use.

Needed big spiral for large book.

These were great for book binding! My kids wrote and illustrated their own book and we were able to get them put together with these!

I have a ProClick punch, but I needed a coil that was large enough for more pages (something ProClick does not offer). I was going to order a 3:1 pitch coil from another company for quite a bit more, but I gambled on using a 4:1 pitch coil, and this works perfectly, and is much more accessible to purchase than 3:1 coils.

They are ok

The product worked as expected. I was just disappointed, and a bit irritated, that the box only came with 95, not the 100 it claimed to have. I had 100 books to bind and I was short 5 and had to buy another box.

These were a great size to bind my 2nd graders memory books with. The spirals were easy to use and durable.
