Thank you for viewing! This is a set of crocheted, kid-sized detachable collars! How about matching with siblings, friends, or family? The yarn is 95% cotton and 5% polyester. It's difficult to see in the photos, but the yarn has glitter in it. Please see the 4th photo for the size. They may look different sizes depending on the angle, but they are both almost the same size. I make each one with care, but as they are handmade, there may be some slight imperfections or unevenness. Thank you for your understanding. Please note that they will be packed small for shipping. They are sold separately for 800 yen each. [Reference] YouTube channel: Chasomeido
