Please note that we cannot guarantee against malfunctions, damage, or breakdowns after arrival. The item has been wiped with a disinfectant sheet at the time of listing, but as it is a used item, there may be some scratches, stains, and discoloration. 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: waterproof protection with a plastic bag and then placed in an envelope, without cushioning material. Please be aware of this. I have multiple items in stock, so if you wish to purchase multiple items, please consult the comment section beforehand. A discount may be possible for combined shipping.
