{"product_id":"mbc-tenprk1k-prn","title":"PRGR New RS DUO Sleeve with Mitsubishi Chemical TENSEI Pro Black 1K Core Series Shaft","description":"\u003cp\u003eMitsubishi Chemical's \"TENSEI Pro Black 1K Core Series\" is a high-performance carbon shaft for drivers developed for professional athletes. Its main feature is a structure that places a highly drapable 1K cloth in the inner layer (core). The 1K cloth, which has a small number of filaments and a dense weave, provides extremely high dimensional stability and reinforcement to the shaft, suppressing unnecessary twisting and meandering.\u003c\/p\u003e\u003cp\u003eOverall, the shaft's soft butt section creates a natural \"loading\" during the swing transition, efficiently accelerating energy towards impact. The mid-to-tip section is designed with high rigidity, making the face less prone to twisting and enabling thick, powerful impacts. This achieves both a repeatable swing and improved distance performance.\u003c\/p\u003e\u003cp\u003eIn addition to the all-black shaft design, the jet-black band creates a beautiful finish that appeals to advanced players. This is the ideal shaft for competitive golfers and single-handicappers who seek consistent feel and directional stability. Experience the reliability of Made in Japan, utilizing the latest material technology.\u003c\/p\u003e\u003cp\u003e＜Specs＞\u003c\/p\u003e\u003cp\u003ePro Black 1K Core
