The listing, FLAT KEYS "OLD" & WEIRD LOOKING has ended.
Old keys , they are FLAT ON THE BOTTOM, but the top is ____/--------\____ and this is the only way I can describe them.
As for the age, All I know is they are old, how old, IDK...
I think they could be a novel piece for a collection, to use in a CRAFTING PROJECT or just let your imagination take over...
They are about 2 1/2 " in length.
