Review: Comb Binding Machine - Have used a comb binder in my place of work for years, now at home so needed one here. This machine is very good and easy to set up and use. It says it will take 12 pages but using 80gsm paper i wouldn't put more than 8 sheets in at a time, so a little more time consuming. The comb supplied are great for a small booklet but mine was only 60 pages and struggled to take this amount. Simple remedy will be to buy size 10 or 12 comb binders which are not expensive. Otherwise fab machine which I hope will give me years of use.
Review: Excellent tool for making presentation booklets - I've used this tool for many years for my booklets. You can create excellent booklets for presentation work or for just keeping files.

## Questions & Answers

**Q: Silly question, once sheets are bound, is it possible to add more pages at a later time? Do the binders open?**
A: Yes you can.The binders are plastic and extra sheets can be threaded into them.Hope this assists you.

**Q: Can you use plastic coil binders rather than combs**
A: No, I really doubt it. The way the machine works is it stretches out the combs so you can load the sheets in and then releases the combs back closed. Can’t see this being able to work with coils.

**Q: How many pages does the 3/8” spine that comes with the machine hold? Can you buy this spine size separately as I can’t find it?**
A: Not very many, don't know exactly - 12 maybe....don't know, haven't tried to buy the small thin spine on its own.

**Q: What is within the starter kit please  does it include the front and back sheeted**
A: It has the machine, some comb binders and some cardboard for punching through to get rid of the oil so it doesn’t mark your paper. No paper, covers or anything else is included.

### ⭐⭐⭐⭐⭐ Excellent tool for making presentation booklets
*by B***R on 20 February 2026*

I've used this tool for many years for my booklets. You can create excellent booklets for presentation work or for just keeping files.

### ⭐⭐⭐⭐⭐ Very user friendly
*by P***. on 10 October 2020*

It really does cut 12 sheets at once and because of its construction you can then immediately put them in the comb where they are held safely until you open the comb again after cutting the next 12 sheets. This aids ones productivity and efficiency. The machine looks and feels well made and in my short time of using it I have confirmed this. I love It! A point not to miss, which I could not find in the otherwise straightforward instructions was that the small .movable lever at the back is not to release the PUNCHED OUT paper box but to adjust the distance the PUNCHED holes are from the paper edge, 3, 4 or 5mm. The chip tray just pulls out, no lock required.
