This is a T1 (unused) yoyo from One Drop YoYos x Toxic String. I purchased it at the time from the One Drop YoYos direct sales website. I only opened the box once to take photos of the yoyo inside. *Please note that since several years have passed since the purchase, there may be signs of aging (scratches, stains, etc.) on the yoyo itself and the packaging. Please purchase only if you understand this.
