The first fineliner that can be combined in any way thanks to a clever system. Not only can you mix your favorite colors, but also the different Link-It writing systems (fineliner and fiber pen) can be easily connected. With the ingenious click system, you can simply snap the two pens together and separate them again. The cap-off ink does not dry out, even if the pen is left open for 2-3 days. The rubberized, ergonomic triangular grip feels comfortable and non-slip in your hand and can also be conveniently held as a single pen by repositioning the cap. The casing is made from 88% bio-based plastic. Ink color: Romantic Red.
