This is a set of two pairs of simple, solid black men's socks suitable for both formal and informal occasions. The left sock is a merino wool blend, and the right sock is treated with far-infrared processing for warmth. The purchase date is unknown, and they have been stored in a drawer. I hope someone can make good use of them. They are thin and lightweight, so they won't take up much space even if you put them in your pocket. They are very convenient to take on trips or business trips. Keeping a pair in your office drawer or car is also very useful, as they don't take up much space and are ready for unexpected events.
