Slime Balls 53mm, 95a Pink Eyes Mini Vomit wheels with white high performance 95a urethane. Vomit mini wheels are a wide asymmetrical shape with a rounded edge on one side and a conical edge on the other giving you a choice of lock-in feel, with a wide riding surface for control on all terrain. 95a high performance urethane offers a more forgiving durometer for rough terrain with easy, consistent power slides and bark you normally get with a harder urethane.
