First of all, I am new to golf, so please understand that I cannot answer specialized questions. I will not sell individual items. This is a request from my father! According to what I heard, this appears to be a rare item, even among Seve Ballesteros clubs. I often see other people listing Seve Ballesteros irons similar to these, with red and blue markings, but this set of Seve Ballesteros irons does not have those markings and is said to be a muscle-back type. I have an acquaintance who works at Golf Partner, and even they said they had never seen these before and were surprised by their rarity. Golf equipment A must-see for mizuno enthusiasts! These are used items, so please judge the condition from the photos. Please refrain from purchasing if you are overly concerned about minor imperfections. Returns, complaints, and issues of item substitution are frequent, so I will not accept any. Please purchase only if you understand and agree to all of the above.
