Product Overview
In short
The Bownet Hollow Flex Training Balls are hollow, flexible practice balls sold in a 12-pack for baseball and softball hitting drills. They come in three sizes - a 6 in. golf-ball-size mini, a 9 in. baseball, and a 12 in. softball - each made of a durable, thick flex material that limits flight and impact force for safe indoor or outdoor use.
✓ Authorized Bownet Dealer — ships brand-new with the full Bownet warranty

The Hollow Flex Training Balls let players take swings without the risk of injury or broken windows. Made of a durable, thick, flexible material, each ball gives instant feedback about the point of contact while its hollow core limits flight distance and impact force, making it suitable for use at the gym, in a basement, or anywhere else space is limited.

The lineup covers three sizes: a 6 in. mini ball about the size of a golf ball (BN-HOLLOW MINI), a 9 in. hollow training baseball (BN-HOLLOW BB), and a 12 in. hollow flex softball (BN-HOLLOW FP). All are finished in a bright orange color for better visibility against grass or bright sun.

Each set ships as a 12-pack (one dozen) and is backed by a 1-year manufacturer's warranty, giving players a repeatable, low-risk way to log reps whether hitting off a tee or from live pitching.
