Normally the Pro V1’s I buy say on the box made at ball plant 3 New Bedford MA. A dozen I bought this weekend says made at ball plant 4 Thailand. One of the things I’ve always liked about Titleist is the balls were all made in the USA. Now I’m sure we can trust Titleist QC no matter where the balls are made, but given the choice I’d rather keep American workers busy making my Titleists.
