## Questions & Answers

**Q: how far apart are the holes?  Precise measurements only, please.  How many holes does the punch do at one time?**
A: The holes are exactly 0,5cm apart, or 1cm from center of hole to center of hole. It punches 5 holes at a time, on a space of 6,5cms. Hope this helps!
It is really good though, I highly recommend if you have the A5 binders

**Q: Why does the video show this is for A4 paper? Is it for A4 paper??**
A: It is for a5 paper :)

**Q: Is there a model that will work with 11" paper? The specs say it's 13+ inches, but when it arrived it was only 9+ inches**
A: Don’t think so. This model was designed for A5 paper (which was my primary reason for buying it) and also B6 paper. Both of these paper sizes are smaller than 11”.

**Q: What spiral coils can I use not associated with a system? Just the coil.**
A: This is a japanese standard measurement. If you buy notebook coils from and/or for japanese use, it will fit.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Useful tool
*by L***A on October 1, 2019*

This was a bit confusing to figure out at first because the instructions are in Japanese, but once I sorted it out it was very easy to use. Note that it will only punch a few pages at a time.I like not having to worry about buying only products that are made for the binders. I have several Japanese 20-hole binders and had been looking for undated calendar pages but been only able to find them with US three-hole-punch. The punch matches up well to the 20-hole binders and I was able to set up my project notebook in good time.

### ⭐⭐⭐⭐⭐ Works great
*by C***G on December 11, 2022*

I love A5 paper, but didn't want to be limited to buying the Kokuyo 20-hole pre-punched stuff, as I like using notepads. This works great and is very easy to use. You *are* limited to only punching a few sheets at a time, however.

### ⭐⭐⭐ Be Careful -- Just because your paper says A5, this doesn't mean that this punch will work!!
*by S***S on April 3, 2024*

While I truly enjoy the inventive functioning of the punch, it doesn't do the job for me.I purchased this punch so I could add pages into my Lilit Lab A5 Aqua Drops twist-ring binders.The registration of the holes is slightly off, so that the middle holes do not allign with the rings.Read the description carrefully. My Aqua Drops A5 notebooks have 24 holes -- and while they say that the holes are the international standard 1/3 inch pitch, it's clear that this punch does not conform to this standard.This was my 2nd bad purchase -- first I bought the A4/B5 punch before I recognized that my notebooks were A5. So, I bougt this A5/B6 punch and thought that all would be well. It wasn't.READ THE DESCRIPTION carefully. Truly, my dissatisfaction is my own fault!
