HAMMER DANGER Bowling Ball
This was found at home, but I don't know anything about it, so I'm asking for someone knowledgeable to take a look. (I've marked it as slightly scratched because I'm not sure.)

Please check the condition in the photos.
To prevent any issues, please only purchase if you understand that this is a used item. (There may be overlooked or unphotographed scratches and dirt.) Please only purchase if you agree to the above. Also, please understand that I will ship it as compactly as possible.
