Slime Balls welcomes the verastile Screw Balls skateboard wheels in a blue 99a urethane and a 56mm diameter, for those that prefer a bigger wheel on concrete. Sporting artwork by Falu Carolei inspired by classic Jim Phillips' graphics, the blue wheels display worm text and a fly on the sidewall while the tread uniquely features repeating silhouettes of house flies - to look like squished remains from a few feet away.
