The Theory from YoYoJam is a budget aluminum yoyo with celcon caps. The caps are similar to the "lateral caps" sold by YoYoJam which have a dimple in the center for incredibly long finger spins. The catch zone is grooved which gives a unique look and feel. The angular shape of the Theory pushes the weight to the rims giving the ability to spin long and stable. The Theory comes with YYJ SPEED Bearing and silicone response.
