RotoGrip Halo Star (overseas)
The Halo series [Centrum] core is now recognized as one of the best asymmetric cores in Roto Grip history. Its cube shape and central radial disc shape create a highly sustained motion that makes it popular for its ease of use and reliability on the back end. The Halo series also includes the first “Halo”, “Halo Vision”, which is “resistant to oil”, and “Halo Burn”, “Halo Pearl”, and the previous work “Halo・Effect” and the lineup have been enhanced. The latest work [Halo Star] has a [Microtrax H18 Hybrid] cover, but it is an intermediate cover between the solid version of the original “Halo” and the blockbuster “Halo Burn” with pearl specifications. Please pay attention to [Halo Star] with moderate oil strength and high controllability while having an aggressive side.
Overseas bowling balls are approved for all sanctioned USBC league and tournament play, but may not approved for PBA competition. Please check all rules and regulations before competition.
