That’s it. If those things hit the ground wrong they’d explode.
I don’t recall if the Offstring was its own yoyo or if you just put the big wings on the Pocket Change hubs. I want to say both were available.
In whichever case, the yoyo sucked and all Ben had to say about it was “making 4a yoyos is hard” . Haha, that was the first and last of their offstring exploits.
