Thank you for viewing! [Maternity Mark] Body diameter: Approximately 4.8mm Illustration diameter: Approximately 3.9mm Thickness: Approximately 6mm The illustration is different on the front and back. The key holder part can be replaced with a ball chain for shipping. I wanted a unique mark, so I created the illustration myself and used it on and off for about two months. Please understand that this is a handmade item before purchasing. I finished it as carefully as possible. For those looking for a maternity mark that is different from others, For those who are a little resistant to obvious maternity marks, How about it? #Let's enjoy the pregnancy period! #Pregnant #Pregnancy #MaternitySign #Prepartum #Strap #Bag #Car
