It pairs the legendary asymmetric Gas Mask Core with the Aggression Pearl coverstock at a polished finish, so it gets down the lane cleaner than the Black Widow solids and finishes with a strong, angular move on medium to heavy oil and transition.\n\nThe Black Widow Ghost Pearl is the length-and-angle member of the Black Widow line. The high-flaring Gas Mask core stores energy for a strong backend, while the polished Aggression Pearl cover conserves that energy through the heads. The result is the Black Widow's signature flare delivered with more length and a sharper finish, all in a striking ghost-white design.\n\nUnderstanding the Hammer Gas Mask Core and Hammer Aggression Pearl Reactive\n\nHammer built the Black Widow Ghost Pearl for clean length and a strong backend from the legendary Gas Mask core. Specifically, the asymmetric Gas Mask Core posts a 2.500 RG, a strong .058 differential, and a .016 intermediate differential for high flare and a defined breakpoint, while the Aggression Pearl cover at a 2000-grit polish reads later than the Black Widow solids and saves energy for a sharp move down lane. As a result, it gives you strong, angular backend motion on medium to heavy oil and transition. The per-weight specifications are listed below.\n\nThe Legendary Asymmetric Core, Shared Across the Black Widow Line\n\nAt the heart of the Black Widow Ghost Pearl is the asymmetric Gas Mask Core, the weight block behind the Black Widow legacy. At 15 lb it measures a 2.500 RG, a strong .058 differential, and a .016 intermediate differential, a combination that produces big track flare and a defined, aggressive breakpoint.\n\nPairing that high-flaring core with a pearl cover is what gives the Ghost Pearl its identity: the same strong flare and shape as the Black Widow solids, but with the energy held later for a more angular finish. Because it is asymmetric, your pro shop can tune the layout to control how clean and how sharp it plays.\n\nA Polished Pearl Cover for Length and a Sharp Backend\n\nThe Black Widow Ghost Pearl wraps that core in Hammer's Aggression Pearl Reactive coverstock at a 2000-grit polish, in a striking all-white ghost design. The pearl additive and polished surface let the ball conserve energy through the front of the lane, so it gets down cleaner than the Black Widow solids and then makes a stronger, more angular move off the friction.\n\nThat clean read and sharp backend make the Ghost Pearl the length-and-angle piece of the Black Widow line: when the solids start reading too early on a drying lane, the Ghost Pearl pushes through the heads and saves its energy for the pins. Leave it polished for length and angle, or take the surface down at your pro shop for an earlier, smoother read on more oil.\n\nBlack Widow Ghost Pearl Specs\n\nRG and differential vary by weight. Specifications provided by the manufacturer.\n\nWho This Ball Is Right For\n\n✓Tournament Players: A strong asymmetric pearl that conserves energy for an angular backend on medium to heavy oil and transition\n\n✓Higher-Rev Bowlers: The high-flaring Gas Mask core and clean pearl reward revs with a sharp, continuous move off the spot\n\n✓Tweener and Speed-Dominant Styles: Cleaner length through the fronts with the flare and shape of the Black Widow line\n\n✓Arsenal Builders: The angular, later-reading pearl to pair with the early-rolling Black Widow solids\n\nGood to Know Before You Buy\n\n·Strong, aggressive motion: This is a high-flare piece built for traction. If you want a controlled, lower-hook reaction, a lower-differential ball will suit you better.\n\n·Ships polished: The 2000 Grit Polish finish runs clean and long out of the box. For an earlier read on heavier oil, take the surface down at your pro shop.\n\n·Asymmetric layout sensitivity: Layout choices shift the reaction more than on a symmetric ball. Match the pin and mass bias to your game with your pro shop.\n\n·Colors vary: Actual colors vary somewhat from the photos shown; no two balls come out of the mold exactly alike.\n\n·Tiny pit holes are normal: A few tiny pit holes in the coverstock are a normal part of the manufacturing process.\n\n·Sold undrilled: Ships without finger holes, so it can be fitted to your hand and span.\n\nBowlersMart Tips: Where the Black Widow Ghost Pearl Fits in Your Hammer Arsenal\n\nWhere It Fits in Your Arsenal\n\nIn the Hammer lineup, the Black Widow Ghost Pearl is the clean, angular pearl of the Black Widow line. It reads later and finishes sharper than the Black Widow solids, so it is the piece you move to as the lane transitions and you want length with a strong backend. It pairs naturally with the Black Widow Mania as your pearl options.\n\nSurface Adjustments\n\nThe 2000-grit polish gives the Black Widow Ghost Pearl its clean length and angular backend. Take the surface down with a lower-grit pad for an earlier, smoother read on more oil, or keep it polished for maximum length when the lanes dry. Have surface changes done at your pro shop for an even, consistent finish.\n\nCoverstock Care\n\nWipe the Aggression Pearl cover with an approved reactive ball cleaner after every session, and deep clean it periodically. Keeping the cover fresh preserves the clean length and sharp backend that define the Ghost Pearl.\n\nEarn points on every Hammer purchase through the Striking Rewards loyalty program.
