Long-term storage item. Unopened. Due to the thickness being over 3 cm, it will be shipped as oversized mail via non-standard postal service. Shipping will be on weekends. (If purchased on the weekend, shipping will be the following weekend.) * Also listed elsewhere, so there may be sudden deletions or cancellations. * I am working, so it may take several days to ship. Please let me know if you are in a hurry. * Waterproof treatment will be applied, and the item will be packaged. * The buyer who purchases first will be given priority. * Regarding the condition of the item, it is a personal opinion. Please understand if there are any oversights. * Please understand that this is a used item and has been stored at home. Also, please refrain from purchasing if you are overly concerned about details. * Cancellation before shipping is possible. * If the thickness is borderline, the packaging will be simplified. * Recycled envelopes and old towels may be used for packaging materials. * Due to being busy, I may not notice your questions, so please ask again if necessary. * I will strive for honest transactions, so thank you for your understanding.
