Thank you for viewing. My child wore this once over their underwear when they were attending a K-1 gym, as it was required for competitions. The tips of the strings are brown, which appears to be from being burned to prevent fraying. This was the case from the beginning (see photo 3). There is no size listed, but it's about 15cm long and 10cm wide. This is a rough measurement. It's about a size M. It was only used once and did not directly touch the skin. Please understand that this is a used item stored at home before purchasing.
