This project was for an autistic boy - the top of the pen features a weighted spinner. And as the name says, you can "fidget" with it, makes for a good stress-reliever.
The parts were amazingly well-engineered. Mediterranean Wave acrylic blank on a chrome Fidget kit.
Very fine pen. Interesting design.
I always used my magnetic vertex as a fidget pen. I would have it in the front pocket of my slacks at work and release the cap and then let it snap back on. I was told to stop it one day when I was in a meeting.
It shows on PSI website but out of stock at the moment. However, I purchased mine from Woodchuckers in Toronto, Ontario, but they are also out of stock.
