Yes, true, Leopold is Korean, however the C boards with Topre switches are made in Japan, though some sources say made in China and inspected in Japan.

I believe Leopold sells a similar line of non-Topre keyboards as well, certainly possible that the cases are manufactured elsewhere and imported/sent to various factories based on switch type.

Regardless, if final assembly/inspection does occur in Japan, it was quite disappointing to receive a keyboard with such an obvious defect, especially at that price point.
