CONDITION: Used for about a year until a few days ago and was working normally. I am selling it because I no longer use it. I think it is generally in good condition, but it is a used item, so please refrain from bidding if you are concerned about the condition. Regarding the condition of the item, we try to describe it in as much detail as possible in the product description, but due to the nature of USED items, there is also a subjective element. Also, there may be errors due to individual differences in size measurements and omissions in the items to be described, so we cannot describe everything. Therefore, please refrain from purchasing if you do not understand USED items or if you are looking for perfection. "We will use recycled packaging materials."
