Kicking mule workshop 1980 selvedge jeans.
Japanese make from KMW early 2000s (1980 is the name of make not year) these are no longer in production but were a popular model well known for the highest quality materials and craftsmanship.
Essentially free of wear, aside from minimal fading, the most visible on the rear pocket as shown.
A pair of jeans that will probably last decades…
