Binding Spines/Coils/Combs: Open & Close Easily Adding Pages for Notebook ，Worklion Binding Machine 30 Ring Diameter 3/8"Binding Combs， Maximum 65 Sheets Multicolor Trimmable Sturdy 10pieces

Love it!!! Will definitely order some more for my business. Had to cut them to fit on the notebook.

I needed to put 50 laminated sheets into two books. This hole puncher came with spines and a zipper, and they completed my project without me having to purchase anything extra. The hole puncher feels sturdy and is surprisingly heavy. My books were longer so I had to punch twice. There are three studs that help you align the page. As long as the side is straight the holes come out perfectly aligned from both punches. There are no instructions for the zipper, but it's not hard to figure out. In conclusion, love the product and I see myself using it to make more educational tools for my kid.

I used these for various products in my classroom.

I ended up returning I struggled with lining up the holes. The coils were nice but not what I would use for a pretty book. I almost kept it for my daughter to make books but needed to get a credit to buy something that would work for me.

Returned didn’t fit as needed 3 starts because of quality.

Didn't have the special tool to open the spine, painful for the fingers to open them. But it's affordable and an awesome thing to have when you like making your own notebooks/journals.

I use these to bind my busy books together. Love the easy open and snap shut. And no catching pages or worrying about metal spirals. 100% recommend

Nice item. Just what I was looking for. Arrived safely and in good time. 2 Thumbs up 👍👍
