Although I haven't used it since purchasing, I've stored it in a cool, dark place at home. However, due to long-term storage, there may be some deterioration. If you are concerned about the condition, please inquire in the comments. I will ship via Mercari delivery, using the dedicated box and flyers as cushioning material (I generally do not use bubble wrap or similar cushioning materials). Please purchase with your understanding. - Immediate purchase is welcome. - This item was displayed in a store. Please refrain from purchasing if you are sensitive to initial scratches, etc. Returns are not accepted to prevent item substitution. - Items sold as a set are packaged and stored, so I generally cannot sell them individually. - To reduce the number of to-do list notifications, please use transaction messages only for important matters. Greetings, etc., are unnecessary. I will not reply if I deem the message unimportant. - Items will generally be shipped within about 2 days. There may be times when I cannot ship due to work, so I have set the shipping time to 4-7 days. If you are in a hurry, please consult in the comments. - The person who purchases first will be given priority, even if negotiations are in progress. - Price negotiations are based on the premise of immediate purchase after the negotiation is successful. Please purchase within 24 hours after the negotiation is successful. If you do not purchase, I will refrain from future transactions and will block you. - If you purchase multiple items, I will offer a small discount. Please let me know in advance in the comments. Also, there may be multiple of the same item, so please inquire if you want multiple. - Please inquire about shipping troubles yourself. - I will change between Yu-Yu Mercari delivery and Rakuraku Mercari delivery at my convenience. If you feel uneasy about the above, please refrain from transacting.
