I'm selling these because I replaced my earphones. The case has been used for about 2 years, so it shows signs of wear. The carabiner etc. haven't been used, so they are new. Please refrain from purchasing if you are sensitive to used items. Shock-resistant case specifically for AirPods Pro, with a lock function and carabiner ring for convenient carrying. - Brand: ROOT CO. - Model Name: Shock Resist Case Pro - Compatible Models: AirPods Pro - Features: Shock resistance, lock function, carabiner ring Thank you for looking.
