The first fineliner that can be combined in any way through a clever system. Not only favorite colors, but also the different Link-It writing systems (fineliner and felt-tip pen) can be easily connected. With the ingenious click system, you can easily 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 the 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: Electric Purple.
