Came across this at TaoBao, I think it's an Off String yoyo because of the specs, and seems like it have this Avant Garde/L4 wall system. Designed by people from the 91yoyo forum, I'm curious how this thing play, and hoping I'll get to try some day.
specs: 84.8mm diameter, 66.3mm/74.25mm width, and 92g.
there's two measurement for the width, I'm not quite sure how it goes, but yea.
Here's a link for those interested.
