GBC Binding Spines / Spirals / Coils, 5/16" Diameter, 45 Sheet Capacity, ProClick, Black, 25 Pack (2515662)

Bought these in 2014 and we still use the exact same ones in 2026. I like that we can make our documents, keep them bound, after the three-year requirement for holding the files, I can open these up and reuse them again for new documents. They hold up very well. Plus, if you notice a typo or a forgotten page you can easily open/close these. Sad that they don't make them in larger sizes.

I love these because they are reusable. The first time you use them, you’ve have to put in a little more effort to get them to close. The tool makes opening them a breeze, and after using them a few times, they easily close up with the tool.

Great

I use 24lb paper because it's a sturdy weight of paper. It holds up better and feels like a better quality than the so called 'normal' 20lb paper. Plus, I buy my paper at Costco in the 800 sheet package for the same price as most stores sell the 20lb paper of 500 sheets which is a standard ream size. With that being said, I bought 1/2" Pro Click bindings to use on the 65 sheet books I'm making. That size is supposed to handle 85 sheets of 20lb. I thought they would be big enough to hold the 65 sheets of 24lb paper, but they aren't. It's hard to turn the pages and you risk tearing the paper. So I then bought the 5/8" Pro Click bindings which is supposed to hold 110 sheets of 20lb. This is the size that works great, looks great and allows for page turning, and opening up the book flat for my 65 pages of 24lb papers. It would allow for a few more sheets if needed.

These work great - demerited because I can't (or couldn't at the time) order more tan a handful in mixed, mostly throw-away colors. What about single color packs of 25, or something? Maybe they've fixed this, but I've moved on to something else.

So happy product was available through Amazon. It was not available in big box store.

As a homeschooling mom, I have used these and similar products for all kinds of books. It is so much more suited for my children and our family in general to have our notebooking pages bound in a spiral book format, but as the nearest copy shop is more than an hour and a half away (and I would probably get lost looking for it), that was just not an option. Last year we used three ring notebooks, but my kiddos are very hard on those, and one nearly broke her fingers getting them caught in the rings. This has been the most wonderful solution. We can add pages if need be like a 3-ring binder (although you may have to use a larger size binding), and they are fairly easy to open/close with out any pinching. Plus the books are soft if they should slip off the couch onto mom's foot (I speak from experience). All in all, I would say the hole punch machine and a selection of these bindings are one of the greatest purchases I have ever made.

I read a review of this on a music teachers website and decided to give it a go. I am glad I did! I have so much loose music and it was really getting disorganized. Once I received the binder and the coils I put off doing it because i thought it would be complicated and take a lot of time. It was NOT! It is so easy. In 15 minutes i had about 100 pages punched and put together in two binders. I ordered the smaller coils that fit 45 pages. I am going to order the next size up. So pay attention to the size of the coil to fit your needs. I agree that it might be a bit expensive but if it holds up, i think it is a worthwhile investment. I ordered cardstock to make the front and back covers. And yes, the little zipper upper tool was included in the box of coils.

Easy to use, professional quality, will purchase again.

GBC ProClick Spine are wonderful. They are simple to use and sturdy. I plan to purchase more of these when I need them.

Son buenísimos, se ponen y se quitan sin problema. Ojalá hubiera más tamaños. Muy recomendarles.

So easy to use and I love the fact that it can be easily opened if I need to remove or replace a page.

Works well, can be used multiple times and can cut to size easily for any project, but due to the spacing of the rings a specific type of punch is required which is quite expensive.
