The Uni RE:3 Biz multi-pen is a Japanese market erasable pen with a dual knock mechanism: twist to choose a color and then push the top button to extend the tip. Like the rest of the RE series, it uses Uni’s thermal ink, which erases when it gets too hot.
The Uni RE:3 Biz (also spelled RE3 Biz) is an upgrade to the standard Uni RE:3. The Biz model has a metal grip which gives the pen a nice look and some extra weight not found in the standard model.
The RE:3 is a refillable, 3-color multipen with ink in blue, red, and black. The refills are 0.5 mm.
The pen uses the URR-103 refill.
