The rubber tips are specifically made for throwing on artificial turf ground or with indoor practice nets. Some U.S. states require that junior throwers use a javelin with a rubber tip. Check your states athletic rules. Great for fine tuning a throwers technique. The 600 & 800 gram is used by High School & College Girls. Colors and designs may vary.
I love everything about it all the way down to the grip and the color. You guys really made me happy. Thanks.Review by Jhon / (Posted on 4/4/2018)This item is very great!
