What's the big deal about Hyper Freehands?

I don’t get it. They’re like 35 bucks and you cant silicone recess them because you cant remove the caps.

Why are they so EXPENSIVE?!?!?!

It has something to do with Duncan buying/selling them the title for that yoyo and them being very rare and such…

I think it has something to do with Bandai making them or something. Yeah, they were something like the freehand 1.
