This is a headband for Seria Dolls (head circumference 13.5-14cm) and 5.5-inch heads. Shape-memory wire is used for the accessory, so it has a spring effect. Since babies' heads are oval, if the ends of the headband are behind the ears, it may come off easily. In this case, please put the headband in front of the ears. I also sell headbands in 1/6 and 1/3 sizes. Size: Approximately 3.8cm in diameter (adjustable) Material: Plastic beads #SnyadollItems
