As the name implies, this pen has many interesting characteristics that make it a perfect companion for people who are always writing on the go. The pen is approximately 20% shorter than standard Tombow multi-pens. It has a slim body diameter of 12 mm, and includes four ink colors. The push buttons for each of the ink colors not only have a different color to distinguish them from each other, but they also have different grooves. This means that over time you should be able to distinguish the different colors by the feel of their button rather than by having to look down to see what you're pressing.
A spring loaded binder clip allows you to attach the pen onto thicker items such as binders and clipboards, and the clip features a hole so that the pen can be attached to lanyards. Multiple body colors and ink refills are available.
This is the Gentle Lilac Purple body. The photo showing the spring loaded clip features the Clear Blue body.
