Rubber O-ring


#1

What is an o-ring and what does it do


(LookAYoYo) #2

an o ring is a cheep response system yoyojam used to use and i think they still do. if you have an older metal plastic hybrid yoyo from yoyojam (Dark magic, XconVict, hitman, speeder, ect…), if you unscrew it and look inside, you may notice a little black o. that is it.
