Callaway X-20 irons and Big Bertha set

Callaway X-20 irons 3 - 9, PW, SW ( 9 irons all up). Callaway Big Bertha woods and 460 Driver. Callaway bag. These were my first set of clubs, which I purchased second-hand, and they've been great. Overall good condition, played most weekends. Selling as I'm looking to upgrade. Would consider selling without the bag. I'm by no means an expert in golf or clubs, but any questions and viewing welcome. Located in Orewa.
