Hello! I've had a Pilot Decimo for probably just around a year now. It's got a F nib, and I have a CON-50 converter installed. I've always used the same ink in it (I believe it's Diamine's Majestic Purple). I've never had any problems with it either, it's worked perfectly! Then, a few months ago (1-2) months, the ink flow just became terrible. It skips, sometimes completely stops, and is terrible to right with. I have to trace my letters five time before you can actually see the entire letter with no skips. I've cleaned out the pen fully (I used just water, I've never used any soap or anything with my pens) and it still doesn't work right. I don't know why it's not working. I really hope I haven't broken it, and I just want my favorite pen to be back to its former glory. The pen used to work so well, does anyone know why it might not be writing correctly? Thank you so much, and dear gosh I hope I put this in the right place.
