This is the Refined type of microfiber hip brief, one of several types available. It has a good texture, is durable, and is a high-quality item. A Calvin Klein store employee in America also recommended its quality. If you purchase a set of 3 colors (red, navy, gray), I will sell it for 8000 yen (an additional 200 yen discount for repeat customers). If you wish to purchase, please apply for a bundle purchase or leave a comment if you have any questions! #skbriefs
