Approximately 29 cm tall x 21 cm wide, 2 mm thick. The seller cut this from a large sheet, so some areas are a few millimeters larger. Please understand. As this was cut by a non-professional and stored at home, it is not perfect. Please understand. Purchased from a handicraft store, this is high-quality felt that originally cost around 4500 yen for 100cm x 100cm. Individual sales: 180 yen per sheet + 250 yen for shipping and packaging + sales commission on the total amount.
