Thank you for viewing from among many! ꕤ︎︎·͜· Polyester/polyurethane cloth mask... handmade. Size is... Length... approx. 11-13cm Width... approx. 9-10cm (from the center) I think it's a size for kindergarten to elementary school children. The elastic is threaded, but it's not tied so it's easy to adjust. To make it easy to tell the top and bottom, a tag or a name tag is attached on the inside near the elastic casing. (Please wear it so that each tag is at the bottom) Please wash it once in a net before use. Wrinkles are less noticeable due to the polyester material, and it feels smooth and comfortable to wear. For those who understand handmade items, thank you! ꕤ︎︎·͜·
