- Brand: OHTO CELSUS - Color: Black - Type: Ballpoint Pen - Cap: Yes - Refill: Replaceable - Refill Type: C-305P (0.5mm) - Ink: Water-based (Black, Blue) Thank you for viewing. This is a discontinued OHTO CELSUS ballpoint pen. I will also include the blue refills I bought with it. One has been used, but the remaining four are unopened. I used it at my desk at home, so it doesn't have any scratches from carrying it around, and I think it's in good condition. Of course, it was stored by an amateur with the intention of using it, so there may be some minor scratches. Please check the photos and purchase accordingly.
