GS01 Needlepoint Ballpoint Pen BlackThe OHTO GS01 Needlepoint Ballpoint Pen Black is a light weight writing tool made from aluminum. The barrel has a cylindrical grip area which gradually changes to a hexagonal barrel. The needlepoint pen is pushed out and retracted with a chunky press button. OHTO's needlepoint pen is 0. 7mm with the tip made from ceramic (instead of the metal ballpoint usually used for pens). The fine tip enables very smooth writing. Refill this pen again and again.
