Unicorn QS Spin Shafts

[Ni518079]

Has anyone ever heard of these shafts. I thought about getting these to try them as I've never seen or heard of them before...but not for that price. They are like slikstix or sidewinders but spinning.

Any info would be greatly appreciated.

yeah I have a few sets with those, they are like the sliks but not bendy but very hard to pull out if you want to change, they are like a steel rod that pushes into the barrel, not screw on.
