Thank you for viewing! ^_^ This is a name tag made of natural leather, exclusive to the Familiar Show. These name tags were originally meant to have names engraved on the back, but I kept this one without engraving because I hadn't decided on my younger child's name yet. My daughter, whose name was engraved on one, used it on her school backpack. Since it's natural leather, it will leave marks if it gets wet, but the color will change over time, developing a more subdued hue. Size: Approximately 8cm in diameter.
