Designed in tandem with Spitfire and Grimple Stix, the semi-translucent purple Sapphires skateboard wheels arrive in a 58mm diameter with a super soft 90a durometer and a radial shape. Offering a smooth ride over rough terrain, the collaborative wheels employ a sparkly glitter throughout the urethane for a noticeable accent. Looking at the wheel's tread, a combination of both company's mascots is printed as a graphic for a co-branded, detailed touch.
