Size 1 Synergy Caps fit the YoYoJam Hitman Hybrid, Axiom and X-Convict. They snap into the side of the yoyo to replace the stock caps and allow you to hold your yo while it's spinning, opening up a huge range of cool grab tricks.

Please note that it can be difficult to remove your YoYoJam cap. A sunction cup can be used, or the cap can be pushed down at one side to 'pop' the cap up at the other.

Comes in pairs.
