This item was purchased on Mercari. I am selling it because I have no opportunity to use it. Size: Approximately 14mm * 19mm Please note that there may be slight variations in size due to personal measurement. Please understand that the color may appear slightly different in the photos compared to the actual item due to the shooting environment and lighting in your room. This is a vintage item, so there may be some minor scratches or stains. Please purchase with the understanding that this is the case.
