This is a bit of a fun Pinball Item, that could be used a Pinball Club Championship Ring, cool wedding band for the die hard pinball head, or just a bit of casual wear.
The outer ring diameter is a traditional 1 1/16" inch ball, with this one having a size 13 which in metric is 22.2mm hole. The hole for your finger is offset so the bulk of the ring is topside on your hand. If you want another size just let me know and I will add it to the range. If you are nerous about purchasing a nice metal ring you could purchase a grey plastic one to check the fit and comfort.
Prices vary based on material and finish, but the polished silver or gold plated brass would be sweet.
