I am selling these earphones because I purchased new ones. They have been stored at home. There are no defects. The ear tips have been replaced with new ones. There are some minor scratches from use. Please refrain from purchasing if you are a nervous person, as these are used items. There is no box or accessories. Returns are not accepted. Thank you for your understanding. ※Regarding payment, we do not accept convenience store payments. We had a previous customer who was not punctual, so if you wish to pay at a convenience store, please consult with us in advance via comment, and we will only accommodate those who can adhere to the deadline. If you purchase without consultation, your order will be cancelled.
