TOPSPIN PRO, perfect for tennis spin practice.

Thank you for looking.
The photos show everything included.
Instruction manual is not included.
Used a few times indoors and then stored in a storage room.
Operation has been confirmed.
There are some dirt stains on the storage bag and mysterious spots on the ball from storage. Please be sure to check the condition of the spots and dirt in the photos and purchase only if you are satisfied.
Other than the spots on the ball and the storage bag, I believe it is in good condition.
As this is a used item, please refrain from purchasing if you are sensitive about such things.
