Bought the Power Support Smart Pen for Li Xiang from Challenger for S$39.90. There are 4 colors available, Pink, Black, Brushed and Stainless. I got the Brushed one.
It is made in Korea and felt pretty solid in my hands. I will not be using it because I don’t or rather I can’t draw on my iPad. I think it is suited more for designers as they can draw better with a stylus than their fingers on an iPad. You can’t control the thickness of the stroke though just by using the pen, if not that would be perfect!
There a 3M logo at the top tip of the pen, I am guessing it is made by 3M but package under Power Support.
