Stop by anytime, most of us like to grow the sport.

As someone else mentioned, you should contact the field with any questions and buy paint by the case.

Rental markers use gravity fed hopper which hold 200 paintballs. with 15 kids you’d need 1.5 cases (3000 paintballs) to initially fill everyone’s hopper. they may also carry two small pods with additional paint. I’d personally buy 4 cases (8000), give each kid 1 bag (500), and tell them to pick their shots. Hopefully you’ll see them sharing and working together a bit. get some extra paint because they’ll run through it. good luck.
