This is a Marty Carey jump cue. I bought it from Marty Carey himself. It's rarely seen in Japan, and even if you have one, it's probably black. As shown on YouTube, it's perfect for jump shots in darts and can jump a distance of one chalk length. I think it's a well-known jump cue that's ideal for jumping short distances. It's discontinued in Japan and not widely available. If you're interested, please comment. Price is negotiable. #jump cue #JUMP CUE #Marty Carey #jump cue
