This item is unopened. Shipping will be via regular mail (teikeigai). I will ship from a small, familiar post office and keep the receipt. Therefore, if the item is not delivered, it will be easier to investigate. However, since it is regular mail, I can only assist with an investigation request, and I cannot offer any other support. If you are concerned, shipping via Mercari's shipping service is also available for an additional fee. 【Days until shipment】 I will ship as quickly as possible, but depending on the timing, it may take a few days, so I have set the shipping period to be longer. If you are in a hurry, please consult with me before purchasing. 250705x10759
