These are 2 bills/bank notes from World Ward 2 Era Japan, and from what I can find on them from other listings they are seemingly from during the occupation of Burma (now known as Myanmar).

This is not a lot, but rather upon purchase you will receive 1 of the 2 bills shown.

Note: I am not a note currency person, so if any information is incorrect it is unintentional. Feel free to message me corrections.
