I purchased this from an authorized online retailer and have kept it in its original packaging. This is a domestic genuine product. Instant purchase: OK Price negotiation: Not accepted If you wish to purchase multiple items together, we can arrange a combined transaction. Even for items where price negotiation is possible, please keep your offers within reasonable bounds (I will not respond to or will block questions that are excessively unreasonable, and this does not guarantee a price reduction). Please note that the buyer who purchases first will be given priority, even during price negotiations (I had a situation where a price negotiation was left unresolved for about half a day, and after another person purchased the item, the original negotiator persistently demanded the transaction; please refrain from such behavior as it is disruptive). I check the condition of the items before listing them, but there is a possibility that I may overlook minor scratches or imperfections. Even for unopened items, they have been handled by someone at least once, so please refrain from purchasing if you are overly concerned about the condition. For items listed as a set, I will not sell them separately unless otherwise specified. The items are stored in a non-smoking, pet-free environment. I may reuse cardboard boxes and packing materials for shipping. Due to work commitments, I may not be able to ship items quickly, so please refrain from purchasing if you need the item urgently.
