The Ohto C-305P Ceramic Rollerball pen refill is a super smooth 0.5 mm rollerball refill in a standard European rollerball size.
While it’s not cheap, this is one of the smoothest rollerball pen refills sold today. It has a metal body and is sold in a 0.5 mm size, but writes much wider thanks to the water-based rollerball ink.
The “ceramic” in the name refers to the material from which the ball itself is made. The super-hard ceramic in the writing ball is very wear resistant, perfectly round, and carries ink well from the reservoir to the paper.
The C-305P is most commonly found as the stock refill in the Ohto Dude metal rollerball.
