This very seldom encountered Vintage Herringbone Twill Fatigue Shirt is certainly interesting. The ROK army was known to utilize everything they had until it was no longer serviceable. With that said, there aren't very many of these in excellent condition.
Each of these have very unique characteristics in regard to insignia (or lack thereof), names, embroidery, and wear/tear. There is a khaki/green (1. Model)) and OD Green color (2. Model).
Condition
Used Good: Will probably not come with sewn-on insignia/patches, will exhibit signs that insignia was removed, writing, embroidery, missing buttons, frays and minor tears.
Used Hand-Select: Will come with at least 1 insignia/patch (2. Model) and be better condition than 'Good' and we will try to satisfy your personal requests.
