I purchased this two years ago. I used it indoors a few times. The machine is in good condition. The balls themselves were used for catch, so some have dirt and worn-down sponge, and are in poor condition. I think they should be fine for use with the machine. I plan to pack it in the box in the photo and ship it in a bag. Please let me know if you have any requests.
