Oddly enough, my partner, who is a designer, asked me 4 days ago "what's that weird moebius wine flask thing you showed me ages ago?" I thought for a while and responded "klein bottle?" and sent her the link to your store. Obviously, the popularity and desirability of Klein bottles follow a curve shaped like a Klein bottle. We're currently in the main volume stage, and will loop back through over the next few years. You should graph your previous sales history. It will almost certainly be indicative of future sales ;-) P.S. We really do love you Cliff, thanks for being you!
