Javelin Throw Turbo Jab Track and Field Baseball Yoshinobu Yamamoto Throwing Practice Beginner

This is a practice javelin for use in junior high school track and field.
It recently gained attention as professional baseball pitchers began using it for training.

The manufacturer is unknown.

There are some scratches on parts of the item, and the sand on the rubber tip might be a little noticeable. However, these are things that naturally happen with use, so you'll likely only notice them at first! It weighs 300g!

How you perceive its appearance is subjective, so please examine the images carefully before purchasing.
I have no intention of selling anything subpar!

Thank you for looking!
