These socks are unsold stock from a clothes shop.
They have been in the shop since the 1950s, and are in good condition.
They have a couple of stitches to hold them together, and the original price tag has been stapled on, as you can see.
If you take the staples off, it may well leave small rust marks behind.
Please bear in mind that these socks are half a century old, and they will need to be treated more gently than modern socks.
You will need to hand-wash them before use, because of their age.
