The world's first-ever water-based Ballpoint Pen, introduced by OHTO, combines elegance with a satisfying writing experience. It features a comfortable, slip-resistant elastic grip and a balanced body for stable writing flow. The ceramic ball tip resists rust and prevents the pen tip from drying using a unique non-drying refill adapter. 

Note: The refill for this pen is compatible with the Water Based Ink Refill C-305 / OHTO
