I've seen some high gloss devices, they looked like chrome with transparent coloring on them. And they had matching tanks too. They were at a local B&M and all I got out of them was they were custom made and expensive, then they guy had to go on a break and left me standing there with another gal so we both walked out without buying anything. I could go back and see if they still have them to get a closer look. We got kind of put off by the lack of service at that B&M. All the attention was with the 20 year olds.
I don't recall any high gloss battery devices. Satin or a few polished is the closest I can think of. If it was a cheap eGo battery, like from FT, you could put a gloss finish on it yourself. I shall hunt anyway.
