The TopYo Quantum is their next entry into the bi-metal line-up! The TopYo Quantum is both great for grinds, horizontal play and speed, at this price it would also be a perfect shape for 3A. The TopYo quantum is the signature of TopYo Korean player Kim Daehyun.

    Great yoyo! Plays very smooth and grinds awesome cause of the finsh that it has. Great price for a bimetal and good quality.

    If they would’ve charged $95.00 for this item would’ve still been a bargain. This is a gorgeous piece and plays well above its price. Hurry and buy this thing. You’d be doing yourself a favor
