This is the 2024 model of the ONOFF KURO irons. It's a set of 6 irons, from 5-iron to pitching wedge. I've used them for about 10 rounds since I bought them new. There are some scratches from normal use. It was originally a set of 6 irons starting from the 6-iron, but I've added a 5-iron as a single. The shafts are Modus 105, and the flex is S. The grips are hardly worn, so you can still use them for a while.
