Jflowers JF-BK1 Break Cue. This break cue features a satisfyingly thick, original Jflowers carbon fiber shaft, delivering impressive power and stability. The durable J FLOWER carbon shaft is made from the same carbon fiber material used in American aircraft. Joint: Radial Tip: Original Tip Size: 13mm The Jflowers BK-1 is a popular break cue, with many users around me, and is known for its excellent cost performance. It seems to be discontinued now. It has been weighted for a heavier feel, allowing for clean breaks even with a light stroke. The weight can be adjusted by removing the added weights. It appears to be in excellent condition with no noticeable marks or scratches. Please refrain from price negotiations. Item...Cue Type...Break Cue Grip...No Wrap
