I have a korean micro ag ceramic pen - standard refill 0.5. the cartridge says permanent ink jg #91001. will this fit in my pen? a gift from a teacher

Yes it will. That was the old cartridge that was in my pen when it ran out.

I have a ceramic roller refill c-300, will the c-305 work as a replacement? What's the difference between 300 and 305?

Yes, I don't know the difference but it works fine in my pen. I think they just changed the pat number.

Does this fit the liberty pen? my insert looks the same, and says c-305 0.6, but says "6c" where the photo of this product says "5l". odd. the liberty

it fit my Micro Ceramic Pen, something I bought at a museum.

Would this work for micro ceramic roller ball pens?

They worked great for me! Janie H, Texas
