I believe they are still based in my old hometown of Palmdale, CA. I need to find the ball cleaner bottle for them again and I'll put down the address.
EDIT: OK last address I have for them is:
Tenth Frame Products
38448 20th Street East
Palmdale, CA 93550
Couldn't find a phone number or web site address unfortunetly.
