TSRUYA Deluxe Heat High Neck, size S. I ordered the wrong size. One has been opened but is unused. These are heat-retaining and heat-generating underwear for winter golf. They are thin and won't interfere with your swing. I'm selling a set of two. One has been opened, and I can't return or exchange it because I don't have the receipt. The original price was 6600 yen each. I'm selling the set of two. They are new, but please refrain from purchasing if you are overly concerned about details. Thank you.
