This is a glass cord and mask cord item from MB. There are no noticeable scratches or stains. There is a part of the chain that has scratches, but it's only noticeable if you look closely. There are no problems with the appearance or use, but those who are concerned may want to refrain from purchasing. (Photos 4 and 5) The following is a quote from MB's EC site: It uses Perlinger's Shrunken Calf, famous as Hermes' leather. The texture of the leather is exceptionally good. In addition, the cord part is made of brass material for lightness and has an allergy coating. When you wear glasses, you can use it as a glass cord, as a sexy and glossy accessory. It can also be used as a mask cord by replacing the attachments on the tip parts.
