Shop descriptions... 😏
"This is a thorough reproduction of the XX model manufactured by DENIME at the time of its founding. The fabric was developed jointly with Kurabo Industries based on recipes from the time. The uneven thread is ring-spun from the same rice cotton used at the time, rope-dyed with a special indigo color, and finished with vegetable dyeing to create a deep texture. A certain DENIME-like color has been reproduced."
I was close to ask you guys what "rice cotton" actually is. You can find it nearly on all shops that carry Denime because they all made a simple auto translation (also for some other brands).
Actually, it simply means "US cotton" and if you don't translate the whole text but the words themselves, it becomes clear.
