Callaway FT-i 25th Anniversary Driver Limited Edition of 2500 with Serial Number – Celebrating 25 Years! The "FT-i Driver" is a concept model from Callaway Golf, celebrating its 25th anniversary. This driver is designed by condensing Callaway Golf's technology from the past 25 years. The limited edition model, released this time, features a black and silver base design, a 25th-anniversary logo, and a serial number, making it a truly valuable item, limited to 2500 pieces. The "FT-i Driver," characterized by its square shape, boasts an "Inertia Moment" value, which represents directionality and straightness (i.e., ease of use), that is among the world's highest levels. Callaway Golf's unique Fusion Technology (FT) distributes weight not only in the rear of the square head but also in the toe and heel. A total of approximately 44 grams of free weight achieves an unprecedented high inertia moment. Thank you for viewing. ○ Everything in the photos is included.
