Skunk2’s limited production, collector item, Mini Oil Cap Keychains were first introduced at Skunk2’s 2008 inaugural Garage Sale and Open House. Skunk2’s machinists produced these as part of a high-speed machining demonstration, and handed one out to all who took the tour. There are currently about 100 Mini Oil Cap Keychains in circulation. Because of their popularity, Skunk2 produced an additional 100 oil caps. We’ll be handing these out at special events and appearances so be on the lookout for Dr. Charles, Dave or any other Skunk2 team member.
