I have a bag that measures 4 3/8" x 7 3/4" from war that contained one bullet and message from US to Vietnamese. Top of bag was to hold a bullet (pictured) and read (in english) "grasp corner firmly and snap" then below "to open along this line". Below the line (separate from bullet compartment) it reads:

chiêu hồi giúp bạn gặp lại cha mẹ, vợ con trong cảnh thanh bình của nước việt tự do, dân chủ. 4-25-69

vDict.com translates to:

rally your help see parents, wife and children in tranquillity of free vietnamese country scene, again democratically. 4-25-69

Then is this information:

8445068
32404
ETHYLENE VINYL ACETATE COPOLYMER
3-70

Can anyone expand on the translation or know more history of this bag?
