This is an IDEMITSU gas station staff jumper (nylon). It's a thin nylon jumper, not for heavy cold protection, so it seems easy to use. It's over 25 years old. It has been stored unused. Designed by Jun Ashida, the IDEMITSU logo is also cool. Size L. Although it's new and unused, it's old. How about it for your collection or everyday wear? Although it is new and unused, there is some deterioration. Please check the photos and consider before purchasing. Thank you.
