Purchased about 4 years ago. There are no noticeable stains, but since two children wore them, the 70cm size may have some pilling and wear, while the 80cm size has relatively less wear. They can still be worn. The 70cm ones were purchased at Nishimatsuya, and the 80cm ones were purchased at Uniqlo. Some have tags cut off. Names written on them have been blacked out with a marker. Sleeve Length: Short Sleeve Type: Innerwear
