The design of this digital input pen for tablets, smartphones and notebooks is based on the LAMY AL-star rollerball pen. 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.
For many devices, there are both stylus-enabled and non-stylus-enabled versions of the same model - if your device did not come with a stylus from the manufacturer, it is best to check again with the manufacturer's customer service whether your device is compatible with EMR technology.
