Thank you for viewing! This is a bandana for medium-sized dogs. It has an adjustable neck with a stopper, which I think is convenient. Both the first and second layers of ruffles are made with two layers of fabric, so it's a bit thick! Neck size: 30-32cm Neck drop: 8cm ◇ Elastic type Adjustable size with stopper There may be slight size variations. When washing, please hand wash or use a laundry net. The folded-over parts are hand-sewn. Thank you for your understanding of handmade items. m(_ _)m
