Aurora Optima ballpoint pen. *I've selected Delta because there's no Aurora option, but it's originally Aurora. Retail price is 60,500 yen. The black pearl color is beautiful. It's a very user-friendly ballpoint pen. I used it about 10 times after purchasing it new, but I've kept it for display purposes since then. I'm using a converter and have replaced the refill with Pilot's Acro Ink, but if you don't want it, I'll return it to the original Aurora refill and send it to you. The included accessories are the original box. (There is only one refill, and no spare refills)
