Inside is a Bowl of rice a small spoon and a Sauce/Stew/Curry to go over the rice. I don't know exactly what each one is and they will be pulled at random by me.
I ate a couple with the JGSDF in 2021 and the 2 I ate were fish. I believe mackoral.
They did not come with the heaters unfortunately, so it is best to heat the rice by warming it in hot water before opening the rice bowl. (The JGSDF Solders boil the rice for a few mins before eating).
I do not guarantee they are 100% since I don't read Japanese so eat at your own risk. I do not offer refunds. However since they came into my possession in 2021 they have been stored in a cool dry place.
These are hard to find. If you have any questions please message me and I'll be happy to answer.
