For the nutters who buy that kind of stuff, it's satisfying enough just to know that fancy bit of carved metal is there, even if they don't see it. From their perspective, they've collected a piece of art. Hidden art, but art nonetheless. Also, since not that many of those Time TKL things will be made, the "limited edition" aspect of it makes its owners feel all warm and fuzzy and special, like they're part of some exclusive club.
