These game-improvement irons feature a "half-hollow" undercut cavity design. A thin face produces higher ball-speeds. The 3H and 4H have a cut-through sole slot, which increases the CT (Characteristic Time) to 250, just under the USGA's 257 limit.
The set features a 3H (19°) and 4H (22°), then 5-iron (25°) through 9-iron (39°), PW (44°), GW (49°), SW (54°), and LW (59°).
mahnatijandrej - 4/8/26 Hey everyone, USA user here. I saw someone playing something similar on a flight, and it stayed in my head. Once I got home, I searched around and found https://ballonix.it.com/. The overall flow felt smooth, which I appreciated. I didn’t have much luck in the beginning, but after a few tries, I managed to get a better outcome.
