Thank you for viewing. Length: Approximately 14.5cm, Width: Approximately 4.4cm Thickness: Approximately 0.2cm, Weight: Approximately 58.6g I have not had the item authenticated for authenticity or material by an appraisal institution, so I do not know the details. A simple magnet test was performed, and it does not stick to a magnet. It has a substantial weight. The condition is used. Please note that the actual color may differ from the photos due to lighting during photography. Please examine the photos carefully before making a decision.
