"UV glowing is perfectly good, and the ink is almost invisible otherwise. It should be noted though, that if a line is too wet, the ink will leave a visible glossy trail as if it's never completely dry.
The only downside was that there seems to have been a small fragment of some alien substance (seems like a curled up thread or dust) inside of a bottle. I believe it to be harmless but will write later if I find it to be otherwise."
Joined a group that exchanges postcards with the message, not the address, written in Blue Ghost. It is a lot of fun. I used a dip pen.
