Is this perhaps North Korean????
North Koreans selling on Amazon sounds a little far fetched...But you're right, the lettering does look korean.
But to be on topic, that color is SEXY!
Company website says Ho Chi Minh city (Saigon) Neck is straight. Mild fret buzz 1st. string 1st. fret little on the slimmer size but I think it's pretty good.

Seems suspiciously cheap for South Korean though. Unless it is some aborted Vietnamese shipment for a South Korean retailer that went sideways and ended up on American Amazon instead.
Can anybody here read the Korean?
Machine translation of the image suggests it says something like "Relationship Sound Music"
My bet is the axe was assembled/finished in Vietnam and the truss rod cover was sourced from Korea which has a significantly larger guitar manufacturing industry than Vietnam.
My guess is the company (executive offices) are in Vietnam and the production is in Korea. For all, we know they could be made in Korea by World Musical Instrument Co. along with the Gretsch, Dean, B.C. Rich and PRS guitars.
