Battles went out of production loong ago, maybe in 2011 or 2012? They didn't have super sticky paint or anything, but they jam super hard. Most notable are the rasta models (probably the first rasta kendama made?), and they had a nice gold as well. Also worth noting: KCN and Kendama China are different companies (Kendama China still exists today, they make the 'Winner' series). KCN made the Battle, the 'Pro' (kinda more obscure, less well known), and a kinda crappy mini.
Congrats on the win! We're throwing a Destroy All Damas Tshirt in as well, I'll DM you for shipping info
