For sale is a single 4-iron. Product Features: • Supreme Feel: Made with S20C soft iron forging and copper underlay, providing an incredibly soft and "sticky" feel. • Super Practical Specs: Equipped with the valuable "Dynamic Gold TOUR ISSUE X100" shaft. • Grip: Fitted with elite grips, but they have hardened due to aging. However, the grip strength and wear are still good. Replacement is recommended. Condition: • Usage: Used only once on the course. • Face & Grooves: Grooves show almost no wear, and the performance is close to new. No rust is visible in the grooves. • Appearance (Important): Due to humidity during storage, some minor surface rust has developed on the face (especially on the heel and toe sides). I have cleaned it, but it hasn't completely come off, so please be sure to check the images. • Practicality: The rust is superficial and does not affect play (spin performance or feel). For those who prioritize performance and specs over appearance, this is a very good deal. Please take this opportunity to experience the unique feel and easy ball launch due to the low center of gravity characteristic of custom clubs.
