I have 30,000 golf balls for sale, The balls are all new and boxed and are 2 piece, 90 compression.
I must point out that the balls have been in storage for over 6 years, and I do not know if balls have a shelf life or deteriorate over time if unused.
They are marked Glowball and light up brightly when put under a flourescent light source, however I used them on my range just as regular golf balls and there was no issues at all, in fact it made them less likely to be stolen as they were so uniquely different from any other balls out there.
I am happy to sell sample/trial boxes for anyone who wishes to test them out prior to purchasing the bulk quantity, just call to arrange.
