Leinuosen120 Pack Plastic Spiral Binding Coils Kit Spirals Multi Size Coils for Binding Binder Combs Spines(1/4 5/16 3/8 1/2 5/8 3/4 Inch,Black)

I love these! They're so pretty, and I like how each size is a different color because it makes it really easy to find the correct size. I have made so many booklets with these!It says they are plastic; however, I think there's a little metal that lines the plastic. Anyway, when you are finishing the booklet, you can clip and bend the ends of the coil. I am very happy with the booklets that I've made with these coils!

I'm a homeschooling mama who prefers to print/bind curriculum myself. Last year I used the GBC Proclick binding machine with their spines and while I love that their spines are easily reusable and I'm able to pull out or add in pages easily if need be, I don't like that they don't hold very much and they're expensive for how many you get. I was originally looking for 3:1 spines that fit my needs but there really isn't much out there unless you want to special order them for a hefty price tag, which I did not. After coming across a yt video showing her system using the proclick binder and 4:1 coil spines I decided to give them a try and I'm so glad I did! I really wasn't sure what size I wanted but I new I wanted bigger ones so I didn't have to split my larger books up into 2 or 3 smaller books like I had to before with the proclick spines. I found this variety pack for around the same price I was paying before while only getting 25spines per pack vs 120 and it's exactly what I needed! They look and feel great now that most of everything is bound! Definitely buying again!

These are a little bit more lightweight than other coils. I’m used to, but they get the job done and the colors are really fun..

good quality. easy to use and well packed.

Easy to use. Lots of sizes included. Organized nicely but wish the sizing was written a little more clearly. Will purchase again when needed.

These work well but the biggest issue I have is that they’re difficult to separate without stretching each of them out. You have to take all of them out of the package to separate them, so just be careful and have a way to label what size they are so that they don’t all get mixed together.

Arrived timely. Coils were as described

The Leinuosen 120 plastic spiral binding coils worked exceptionally well for my application. I try to keep certain documents together and this was an inexpensive way to do so. They are colorful and would work well for teachers or other institutions that need to separate documents for any number of reasons.
