Good news! Especially to the places which experience frequent power interruption and to the people who are always annoyed by unfinished works. This new pen with embidded light emitting diode(LED)attached at the end of the pen illuminates as you write. So even in the dark, you can still write and finish your work! It has different variations of light color. It is powered by a lithium battery. Try this!
