I think pwest is the winner of yesterday! That looks great, a steal at the price like saskatchewanian says.
With all the models of Koxx unicycles on sale at Amazon and elsewhere, my old guess was that someone had picked up the rights to the brand name and started producing them again. After all, Schwinn bikes and unicycles are still sold even though that company ceased to be in 2001. It seemed like there was too much Koxx inventory out there for it to all be left-over new old stock. But yours sure looks like it’s from the day, so maybe there really were that many Koxx unicycles left in warehouses. Could it be that inventory management practices like that had something to do with why Koxx is presently a bankrupt former company?
Take a look at the Where are unicycles manufactured? thread. The authentic ones were made in Taiwan, like all the well-known brands of unicycles are.
From what I read, Asian knockoffs these days are often made on the same production line as the genuine article but aren’t listed in official accounts, and just go out the back door of the shop instead of being shipped to the official distributor. But someone who’d go to the trouble would likely pick a brand like Apple, Nike, or Beats–something lots of people would recognize and want to buy–and maybe not so much a two-years-dead (and not much mourned) unicycle company. I don’t think you need to worry too hard about that. 
Have fun with it. I love the colors.
