With its rollerball refill, the LAMY tipo writes just as fluently and accurately as one would expect of any Lamy pen. And it is ready for use instantly. This is because instead of a cap, it has an integrated clip-push mechanism which makes for extremely swift selection. When the clip is pressed to extend the rollerball tip, the clip itself retracts into a slot in the shaft, meaning that it can no longer be used to clip the pen onto a (jacket) pocket. When the top of the clip is pressed, however, the rollerball tip disappears inside the body and the clip returns to its original position
