Our rubber lacrosse ball meets NOCSAE and SEI standard. If you need, we can assist you to obtain these approval logo to the balls. Our standard package is 6 balls per poly bag and 120 balls per master carton. We can load 102,000 pcs (850 ctns) per 20’ container. We have our own lab to do the necessary quality inspection to meet NOCSAE and SEI standard. No need to send samples to the specified US lab for the test for all lots.
