Review: Ultimately a money saver. Allows you to use whatever ink you want. - Works very well. The well only fills half way up by design. I think buyers should know this. It is not a problem, but you won’t have as much ink in the pen as with a cartridge, but I don’t mind refilling it. It only takes a minute.

## Questions & Answers

**Q: Would someone please explain how this works?  i understand a converter is used so i can use other bottled inks.   how do i use it?**
A: Put the converter inside the pen (just like a cartridge), put your pen's nib inside the bottled ink, and then screw the converter's screw mechanism at the back, It'll vacuum the ink into the converter just like a syringe. Tip: for a better fill, screw and unscrew a couple of times so no air is left while filling.

**Q: Will it fit in a pilot Kakuno?**
A: Yes. The con-50 and con-70 also fit. The con-40 replaces the older con-50

**Q: Will this fit pilot mr animal collection?**
A: This converter fits all modern Pilot pens, except a few sold in parts of Europe which are altered to take International style cartridges.  I'm not sure if those can take a Pilot converter.

**Q: Does it work with any pilot fountain pen?**
A: No, this does not work with all Pilot fountain pens. I'm not sure how familiar you are with fountain pens, but some fountain pens, like the Pilot Custom 823 have built in ink receptacles that are vacuum or piston fillable. So you couldn't use this converter with those. But you can use this converter in any Pilot pen that uses ink cartridges.

### ⭐⭐⭐⭐⭐ Works beautifully
*by P***R on June 6, 2023*

I bought this for my Pilot Metro, and it has done wonders for me. If you're having the same issues I was, this will solve your problems. (Details at bottom if you're interested.) Pros: NO LEAKING, can see ink level, easy to use* Cons: None yet:) Indifferent: relatively small capacity, but I'm getting about the same amount of time between fills as the squeeze converter. Nothing noticeably different.; I can hear the metal balls moving around sometimes, but it isn't distracting and it's quite soft. I don't hear them when writing -- only when i flip to pen over or set it down or something *I've seen where many people are having issues filling it all the way. You have to fill it, push the extra air back out, and then fill that leftover space again. Goulet has a good video explaining it I've had my metro for several years, and I've always used to squeeze converter that came with it. It leaked TERRIBLY -- so much that I stopped using the pen for a while and ended up buying a different brand pen. I scoured the internet for ways to keep the converter from leaking into the pen barrel and subsequently all over my hands, and I never found a solution. The common consensus is the squeeze converter doesn't have a tight seal, so it leaks. I bought this converter and BOOM problem solved.
