Pilot Con-20 And Celluloid Pens

[R_Bones]

I have a Hakase in jade green celluloid. It can accept a CON-70 but for a variety of reasons I am not the hugest fan of that converter, and the CON-40 is pretty lacking in ink capacity.

 

I have always liked the CON-20; they have good flow and filling and cleaning them is a breeze. Should I be worried about outgassing though if I leave one in a celluloid pen? I am not sure what the sac material is made out of but I know that sacs were known to cause discoloration in older colored celluloid pens, which seems particularly noticeable in green celluloid pens. With that said this celluloid stock is considerably more modern than what those pens were made of and possibly more stable. The color is absolutely stunning and although I assume if it were to discolor it would be many years down the line, I would rather mitigate this as much as possible.

 

Any thoughts on this would be most welcome!

why not refill the cartridges with a syringe?

in the end, it's less troublesome that cleaning a CON-70, and you have the capacity ...

The cartridge refill is an option, it's just a bit of a pain. Two nice things with the CON-20 are they are super easy to clean out and they make flushing the nib and section out a breeze as it's a squeeze converter, so I was kind of hoping it would be an option.

 

I dug around a bit and it turns out there have been versions of other pilot squeeze converters that came in rubber (very bad) and PVC like the old 51 Aerometrics. The latex ones I know will outgas over time but I am not sure how the PVC ones would affect celluloid, if at all, and I am unsure what the CON-20 uses or even if it was ever available in both.
