Five (5) vintage plastic billiard balls in good, playable condition. I believe they are Bakelite. I washed them in soap and water, but perhaps some other kind of cleaner would remove more of the soiling. I leave that up to the more knowledgeable collector. There are two solid balls, #4 and #7. There are three striped balls, #9, #12 and #15. I took pictures of both sides of the balls.
