While clearing my closet, I came across an unopened box of 2017 ProV1 balls. They have apparently been there since they were purchased. As this is a climate controlled environment, will these balls still be usable? Thanks in advance.
Hit a perfect 5 iron from 194 yds on the 15th at The Golf Club at South Hampton. Could not see it go in but I knew it was close... Pro V1x Left dash.
