A simple design, light metal body with lacquering overlay finishing. Slim body with diameter of about 10mm, durable push button mechanism. Good balance of weight for grip, and center of gravity is forward for good stable writing position.
The ballpen uses the oil-based refill that adopted the "Acroinqui" feature of smooth writing.
Why Acroine ink?
"Acroine ink" is about 1/5 of the ink viscosity compared to Pilot regular oil-based ink. In addition, by incorporating a lubricant, by reducing the frictional resistance of the ball at the pen tip, the rotation became smooth, realizing a smooth and dense handwriting. Of course, it's outstanding water resistance unique to oil ink.
