Multitool Ball Sizer .68 Cal, different colors
The Ball Sizer from HK Army is a handy little helper for every player.
Using the nine different hole sizes you can determine the size of the paintballs and find out which back is best suited for your paint.
In addition to the Ball Sizer, this little all-rounder also has a bottle opener, box opener as well as a tank regulator extender wrench.
In order not to lose your Ball Sizer, you can attach it to a belt, rucksack or lanyard with the help of the included carabiner.
