This was a tiny promotional souvenir from Manhattan Rubber bowling balls. It is 2 inches in diameter and comes with a little ring to display it on. The ball has scuffing and comes apart at the seam in the middle. Not sure if it was supposed to or not but could be easily be made to stay with a spot of glue. It is a collectible all by itself but included is a tiny bowling ball bag that the ball fits in. Not sure the bag was part of the set but it is in nice condition and super cute!
