With the world's smallest ball size of 0.28mm, the Jetstream Edge has been recently added to the main Uni Jetstream product line, famous for its smooth composition and fast drying. Lately, the requirement for the fine print of oil-based ballpoint pens has expanded, and Uni has started creating and building up a super fine ball measurement of 0.28 mm. The world's first superfine ballpoint in the oil-based ballpoint pen classification, 0.28mm. The drawing line width is more slender than the gel-ink ballpoint pen with a similar ball width. It uses low-thickness oil-based ink, "Jetstream Ink," so it has incredible fast-drying properties and can easily compose thick, clear lines. The body pivot is intended to communicate the slim and sharp picture of the 0.28mm ball distance across attracting line in a trendy way and centers around useful angles, such as dependability during composing.
