Titleist Pro V1 Test Golf Balls from Lostgolfballs.com
Found an interesting product on lostgolfballs.com the other day - Titleist Pro V1 Test Golf Balls. The product description states "Mint condition golf balls from product development. Same as Original 2018 Pro V1 golf balls. Only have an additional "TEST" printed on one pole of the ball". I was skeptical but ordered a few dozen anyway and wanted to share what the inside looks like after cutting one open (pictures attached). I've yet to play with them so I can't comment on performance / feel, but the internals look identical to a regular 2017 Pro V1.
