Pilot Limited Edition Frixion Point Knock 04 Black Star Story Gel Ink LF Refill, 0.4mm, [Ursa Minor]

Product number: LFPK-30S4S-KOB The FriXion Point Knock 04 is an ultra-fine erasable ballpoint pen that combines the features of the FriXion pen, which erases when rubbed, with the features of the Synergy Tip, to achieve a smooth writing experience and a smooth writing feel. The Synergy Tip is a tip structure and shape that combines the advantages of both the Pipe Tip, a fine stainless steel pipe designed for fine writing with a recess at the tip to support the ball at a point, and the Cone Tip, a cone-shaped tip used in standard ballpoint pens that provides strong tip strength and stable writing.
