These are a one-off custom set of EPCO tournament professional billiard balls (EPC1050). Each ball has a custom emblem on it: 1-7 has a Mitsubishi emblem, 9-15 has a Subaru emblem, the Cue ball is an Evo8 steering wheel and the 8-ball is a check engine light.
These were custom made for me 5 years ago and have never been used. $200 shipped in the continental states. feel free to email or PM with questions.
