Red writing Pro Penn's?


New User
I picked up some balls (that got left on a park court) that I really like, but I can't figure out exactly what kind they are. They say ProPenn in red with the number in black. When I google ProPenn online I see several different types but the photos only show the sleeves, not the balls, and the photos I do see of the balls show ProPenn in black or green, not red. Can anyone steer me in the right direction? Thanks!
