Convenient and accurate 1

A highly accurate stylus to write and draw on smartphones or tablets.
The tip is particularly sensitive to pressure and precise (and plastic protection disk allows not to scratch the screen!) By cons, make sure to keep the disk still in contact with the screen otherwise it 'n' not writing ". So you need a little practice before coming to master the craft.

Otherwise, elegant design, seemingly rugged construction and good finishes (the pen has a certain weight, which allows to gain precision - light pens tend to "go" with the movements of the hand, a heavier pen is more stable).
