Vintage Gibson Strings - Hi Fi Flat Wound and Mona-Steel (1960s)

Here for sale is a vintage Gibson strings box with two strings included. The strings are visibly in good shape. The flat wound string is probably still usable. 

Assuming the packaging is correct, this box includes (1) "E or 6th-Wound Hi Fi Flat Wound" string for Guitar and (1) "E or 6th-Wound Mona-Steel" string for Electric Spanish Guitar. 

Cool for a Gibson collector or would make great crafting/junk journaling material.
