This is a handmade triangular bandana in a small size. It is made from blue oxford fabric. It is a single layer. Length: 28 cm Head circumference: 52-55 cm The elastic part stretches approximately 5 to 7 cm. While there are individual differences in children, I believe this would be suitable for children from kindergarten to lower elementary school grades. The pattern placement may differ from the photos. As this is a handmade item by an amateur, it is not perfect! We kindly ask for your understanding before purchasing. It will be shipped via standard mail from Hokkaido. If you are in a hurry, we can change to Mercari便 with tracking for an additional 120 yen. Please leave a comment!
