The first fineliner that can be combined in any way thanks to a clever system. Not only can you connect your favorite colors, but also the different Link-It writing systems (fineliner and fiber tip pen) can be easily joined together. 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: Blackforest Green.
