Naigai Baseball (Catch Ball Only) 2 Balls

Naigai Catch Ball Only Ball

Set of 2 balls

We highly recommend this for children who are new to baseball and want to start with catch ball.

It looks like a hardball and may seem hard, but it is actually made of rubber.
It is softer and heavier than a soft baseball, but it has elasticity.

We believe this is better than a soft baseball for learning how to grip the seams properly with your fingers.
