Please note that we cannot guarantee against malfunctions, damage, or breakdowns after the item arrives. Since this is a used item, there may be some scratches, stains, or discoloration, although we wipe it down with a disinfectant sheet when listing it. Please check the images carefully before considering a purchase. For packaging, we plan to ship via Yu-Packet Post. Due to thickness restrictions, we will use a simple packaging method: waterproofing with a plastic bag and placing it in an envelope, without using cushioning material. Please be aware of this. We have multiple items in stock, so if you would like to purchase multiple items, please consult with us in the comment section beforehand. We may be able to offer a discount for combined shipping.
