The best things come in small packages! GoSports Mini Foam Baseballs are the ultimate training aids for skilled players looking to improve their swing. The small 4cm size provides a smaller target than a standard baseball, forcing the batter to concentrate and swing with greater precision. You can also take your practice indoors without hesitation! Lighter and softer than regulation baseballs, these mini foam balls are safer both on and off the field. Use the baseballs with a complementary pitching machine, such as SKLZ Lightning Bolt, or by hand for soft toss training. We've included 20 baseballs total and a mesh ball bag, so you can easily pack up and take them to any practice. Develop greater hand-eye-coordination and take your batting skills to the next level with GoSports Mini Foam Baseballs!.
