L.L. Bean Sheepskin Shearling Suede Moccasin Lace Slippers Size 5

There is a pair of L.L. Bean Sheepskin Shearling Suede Moccasin Lace Slippers Size 5, these were gifted to me but sadly they are not my size. They are very clean they don’t look like they’ve been used I do have the number 518 written on the bottom for some reason
