Optimus goes to great lengths to hide the origin of this stove. I have read that it's made in China or Taiwan, but the only markings on the stove or the box are Sweden. It's a pretty good stove (not as good as the Swedish ones). It does not simmer well at all, and the cup is not snug on the windscreen. If you need to make a quick cup of coffee or tea or just boil some water while out and about you could do a whole lot worse.
