YONEX Vibration Dampener WHAT'S THE SCORE!

I am selling this item because I purchased it new but never used it and kept it at home. The packaging is slightly faded, but I believe the contents are fine.
Please refrain from purchasing if you are sensitive about items stored at home.
YONEX's Vibration Stopper 5 and 4, excellent for vibration absorption. Tennis score counter.
