50 Pack Plastic Spiral Binding Coils 4:1 Pitch Spiral Binding Machine

These spirals work great! I have made lots of learning booklets for children and they hold up very well.

I loved the different sizes available because I wasn’t sure what size I would need for the project I was making! They’re easy to use and made very well.

These coils are a good value for the money. They are very light, but appear durable.

Perfect for binding Bible class material and books. Easy to use with the binding machine I bought from Amazon. I don’t remember the name.

Great coils for reports and projects. They are strong and smooth. Do anticipate that the shipment comes looking like they're all mixed together in chaos - but are actually organized in their own bags. I do wish they came with a box to make storage easier, but overall there performance is just right.

Well sorted! Is fantastic they came well packed in 4 different sizes, also seems very durable, sturdy enough for hold together your binding leafs, soft enough for flexibility.

I make notebooks and these were perfect! Love the size assortments!

It’s a nice mix of sizes, but the 2nd smallest size are completely unusable as they’re bent and the spirals are not uniform.
