Oh, sorry, I'm a jeweler, so I just just whipped one up from scratch. However, the copper one was a bit of copper tubing used in plumbing. Just hit it with some polish, and it'll shine... for 20 minutes. Then hit is again. LOL. Copper is the worst at keeping a polish.
My stems were both too thick and too long IMO, so while I was going to have to bore it out anyway, I also chopped back the stummel to make it feel right on my face.
Nope, I like the cob look, chispa, I'm not a fan of coloring the cob away.
Funny thing though. My girlfriend told me that the colored stems made the cob look cheap. I was like, "cheap? It's a freaking corncob, LOL."
