A new ball is non-celluliod ball. They said ban on celluliod balls ,I never heard of it, we used the ball for 50yrs.to make them might be cuase some health problems when using chemicals,but they have safety procedures.they went to a plastic balls before the celluliod. just like glue , they ban the use of toxied glue ,and they said it kill a player , but did not unles he or she was sniffing the glue.if they read the label don't sniff it ,don't. same as manufacturing celluliod don't smell the chemicals. and we don't have to buy new balls ,nets & robots. It will cost us $2.50 a ball if not more,nets.$50, and robots $800-$ 5000. 38mm-40mm- and future 42mm ball.
