Size: Approximately 57.8cm long, 5.4cm wide. I am not an expert, so I cannot confirm if the sound is normal. There are visible scratches. Shipping and replies are not available on weekends and holidays. Also, we may take long vacations during the summer and New Year holidays, etc., so we will announce them on our profile page each time. Please be sure to check for any issues to prevent problems. For items with included shipping, we may change the shipping method. Thank you for your understanding.
