The design of this LAMY digital pen is based on the LAMY AL-Star rollerball pen and features the metal clip. Endowed with Wacom’s patented EMR technology, the LAMY AL-star black EMR doesn’t need a cord or battery to function, and never needs to be charged. There is no difference from traditional writing instruments in terms of haptics, ergonomics and usage, so no retraining is necessary. This is the PC/EL nib which is best suited to glossy surfaces as it's quite a pointed nib. This LAMY digital pen is under two year warranty.
