WW2 Japanese Soldier personal effects For Sale

Not knowledgeable on this stuff, so I will do my best. Battlefield pickup, of personal belongings of WW2 Japanese Soldier, I assume. Paper with all the stamps, appears to be a "Postal savings passbook" Chopsticks with box, appears to be more fancier than the standard soldier's Chopsticks and box. Box is broke on end, but piece is there for repair Hanko Stamp, has 2 ends of different designs. Red paste is dried. Case was being eaten by insects I assume, for voids in cover and top of container. Personal pictures of Family, faded, probably things got wet on duty. Military release form, of individual bringing back from conflict area. Wallet, is fabric outside, and looks like some kind of thin skin pockets on inside. Edge opens up like a regular wallet. Will be shipped insured.
