Hammerheads have been obsessed with the Obsession Tour since its release in February. The Obsession Tour provided an incredibly unique ball motion, and bowlers have wanted more of it, but for lanes in transition and breaking down. The Obsession Tour Pearl glides effortlessly through the body of the lane and has an aggressive motion continuation movement throughout the backend and through the pin deck. The Obsession Tour Pearl is an all-gold ball that Hammer fans will love! Featuring DOT Technology, which allows you to drill anywhere which makes this ball even tougher.
