To prevent problems, we strictly refuse to do business with those who have a history of significant issues in past evaluations. If a purchase is made, we reserve the right to cancel it immediately based on our judgment. These items have been stored away for a long time, but I'm selling them now as I declutter. Some items have barely been used, while others have been used for several hours. There are also some items that were purchased used. Therefore, some instruction manuals may be creased. Basically, I'd prefer to sell items in bulk, but if there's something you don't want, please consult with me first. Feel free to ask any questions.
