## Description

Length with a Vengeance.

When the lanes call for length and a violent backend, the Zero Mercy Pearl answers with authority. Designed to complement the Solid perfectly, the Pearl utilizes the same aggressive Super Offset core, paired with a cleaner, faster-reacting version of the all-new HK22C² coverstock. The result is everything you’d expect from a high-performance shiny asymmetric ball—easy length, a sharp change of direction, and explosive continuation through the pins. Poured in classic Hammer colors and loaded with attitude, the Zero Mercy Pearl delivers no apologies and no forgiveness.
