I am not an expert, so I don't know the details. I have only confirmed that it powers on, and I haven't checked anything else in detail. It has normal signs of use, and there is some soiling due to personal storage. All photos show the current condition, and please bid only if you understand this. [Notes] Please understand that there may be oversights due to my amateur inspection. I am an amateur packer. I reuse (recycle) boxes, cardboard, and cushioning materials. * There are individual differences in how people perceive the condition of the product, so please understand that it is a "used item," and refrain from purchasing if you are a perfectionist or looking for a perfect item. Product images may differ slightly in color and texture from the actual product. Furthermore, we cannot accept returns or exchanges to prevent swapping, especially for precious metals. Thank you for your understanding.
