This is a set of two Aquascutum undershirts, size M. Both are made of Egyptian cotton, one being "kyonen" (strong twist) and the other "80-count fine knit." * Round neck, short sleeve, kyonen, 100% cotton * Round neck, short sleeve, 80-count fine knit, 100% cotton Unlike U-neck or V-neck shirts, these aren't ideal for shirt styles, but they give a youthful impression, suitable for professions requiring ties or for private wear. Purchased at a department store. I believe I bought them around the same time. The salesperson suggested I choose between "kyonen" and "80-count fine knit," and I couldn't decide, so I bought both. Both are high-quality Egyptian cotton and made in Japan. Both can be worn year-round, but the fabric has a substantial thickness. 【Made in Japan】 Manufactured in Japan with high-quality control. These are reliable products. They seem to be made in Wakayama Prefecture, known for its excellent sewing techniques. * Brand: Aquascutum * Size: M * Material: 100% cotton * Made in: Japan * Chest: 88-96cm Please understand that these are unopened items that have been stored at home.
