This is an obsolete, older model shoulder pen holder, angled type. The flap shape differs from the current model. It's similar in style to the shoulder pocket of a combat shirt. Velcro is placed on the surface, allowing you to attach your favorite patches. Rubber bands are placed inside to hold pens. The pocket can store small notebooks, etc. There is some deterioration from use (such as sun-fading on the Velcro surface). Please purchase only if you understand this. #Airsoft #SurvivalGame #Military #JSDF (Japan Self-Defense Forces)
