Important notice: In recent transactions, there have been several cases where the receipt notification was not provided for more than a week after the product arrived, and all communication was ignored, resulting in forced closure by the administration. Basically, I would like you to provide a receipt notification within 24 hours of receiving the product, or at the latest, within 48 hours. However, if you have special circumstances such as travel or illness, please feel free to contact me via comment, and this will not apply.
