Whether your dog chewed up your last remaining ball or you accidentally threw it in the blender (it happens), we've got you covered. Spikeball Weekender Replacement Balls come in a pack of two and make a great addition to your gear. The balls are bright yellow making them easy to see and track in any playing conditions. The grippy outer material gives you enhanced control of the ball (meaning extra-long rallies). Stock up on spares so you don't get caught out!
