Auldey Blazing Teens 3 Offstring yoyo

 a pretty solid piece of offstring yoyo i must say.
it... plays like a rock. when it drops, you'll be more wary of whether it leaves a crackline on the floor, rather than taking a look at your yoyo. i mean, seriously.

 pretty heavy. but feels very solid.
and... its hub-stackable with Auldey's side spinning kit.

 it uses shims, the flat one is the shim, the one with the step is the spacer.

 all these super thin stuff you see here are also shims, of the same thickness i suppose, but u add on to increase the thickness, another word, you can choose to add these on to the shim thats already in there, or replace them with these.

thickness comparison.
