M10 6-bit encoding ink

I'm trying to find a black pen that's compatible with the M10 6-bit IR sensor. I personally don't own an M10 but have sent a 6-bit encoder to a YouTuber with an M10 that is having issues encoding their lenses. The pen I use and that works perfectly with my M11 (Pilot DR pigment drawing pen) doesn't seem to work for his and I wondered if the IR sensor was different for the M10 and therefore the ink required is different? 

If anyone has encoded their lenses and use them with an M10 or M10-R, if you can remember what pen you used can you let me know so I can get one ordered up for him.

Thank you.

Initially I used a Sharpie pen which makes a black enough mark for the sensor but will wipe off quite easily.  I then remarked them with a Markal Dura-ink Needle Nose thanks to advice from another member here.  The Markal appears to be more permanent.  Both markers could be reliably read by my m10r.

Sharpie so far, no problems with the M10. Except it wipes off after a while. Voigtländer lenses are easier, as they have this little ridge that doesnt come into contact with the mount.  I'll have a look at the other options mentioned here for a more permanent mark.

I filled in the small gap over the screw head with with white "correction fluid" (from typewriter days} and they coded fine.

I've experimented with numerous pens and paints, but this particular pen consistently delivers, and it's also budget-friendly. Its matte finish is essential for the Leica 6-bit reader, and it works seamlessly with M9, M10, and M11 cameras.

Yesterday, I used a free, 3D-printed 6-bit template, which proved to be 100% accurate, and paired it with this pen.

Brilliant, thanks everyone I'll order up those pens and give them all a run.

With enough dirt or ink in it, that screwhead will sometimes code very nicely for a 90mm f/2.8 Tele-Elmarit-M v2 - all by itself. And "permanently," since the screw is protectively recessed like some of the Voigtländer/Zeiss ZM flanges.

Unfortunately, it will sometimes also identify 28s, 21s and other 90s as a "Tele-Elmarit-M v2" as well - since they all share the same frameline flange type. Thus requiring white paint fill.
