## Features

- Due to unprecedented demand across the industry, causing a shortage of shafts and grip, we may need to substitute for an equivalent premium shaft/grip.
- Big Bertha B-21 is the first Big Bertha Iron with our A.I.-designed Flash Face Cup.
- This industry-leading Flash Face Cup is in each club. We’ve created high ball speeds and increased spin robustness with a sophisticated face architecture that’s unique to every loft.
- This club profile is engineered to give you more confidence over the ball with noticeably wider soles. For easy launch, lower spin and straighter shots, we’ve added more offset.
- We’ve added a significant amount of custom tungsten weighting. So we can deepen the CG in each iron with extraordinary precision, while still maintaining ball speed in the Flash Face Cup.
- Our patented urethane microspheres comprehensively absorb unwanted vibration for exceptional feel, while also maintaining fast ball speeds.
- Included components: Irons Set
