Product Review (submitted on 1 July 2017):
On opening the box, I was quite surprised at what the gimmick was. However, on watching the video, I realised how brilliant this this is! I've tried making no-write Sharpies many times, but it never works properly. This one is a brilliant design, and it's going to get plenty of use! Highly recommended.
