Thank you for viewing! This is a crocheted, kid-sized detachable collar. The yarn is 100% cotton for the yellow, and 95% cotton, 5% polyester for the ivory inner part. It's difficult to see in the photos, but the ivory yarn has glitter in it. Please see the third photo for the size. Each item is carefully and meticulously made, but due to being handmade, there may be some slight imperfections or irregularities. Thank you for your understanding.
