Javelin Throw Yellow-Green ① Turbo Jab Track and Field Baseball

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.

This is not an unused item. There are signs of use on the fins, but I believe it is still suitable for practice.
The rubber tip also appears to be in good condition.
