Not sure which one to choose? Try both. This combo set includes both the Green and Gray versions of Ghost Chalk, allowing you to feel the subtle difference in response and discover which one best elevates your game. Both versions are engineered for total consistency, maintaining their exact performance from the first day to months later—completely unaffected by humidity or varying table conditions. They coat smoothly and evenly, stay on your tip longer, and significantly reduce miscues without leaving messy residue on the cue ball, cloth, or your hands. Designed for ultimate versatility, both formulas deliver incredible grip on playing tips, heavy break tips, and jump cues alike. Each piece features the signature butterfly-shaped body that sits securely on the rail without rolling away while fitting naturally in your hand. Used in high-level competition by world champion Fedor Gorst, this combo pack is the ultimate way to test both options and find your perfect match. (Note: Both pieces feature the upgraded magnetic-ready metal bottom plate).
