Translated from Japanese:
The Black Widow series is said to be the most favored ball series by bowlers in the world today. The Black Widow has now achieved the forbidden match that hammer fans around the world have been waiting for and hoping that it will one day come true. Equipped with the HK22-Cohesion Pearl, which was used in the "Effect" that continues to sell around the world, the Black Widow Nightmare combines powerful braking performance with the running of a pearl-based ball and the power of new material additives, as well as a powerful back-end motion of a different level. Moreover, like the effect, it has a maneuverability that makes it difficult to feel the influence of oil at the back of the lane, which is impossible with other pearl ball-type balls, and it is a ball with powerful potential and aggression that can be said to be a nightmare for opponents.
