We check the precision of the parts during purchase. Although the item has been opened, it has been stored in its box in a cool, dark place, so I believe the condition is good. Since it's from about 20 years ago, the outer box may show some age-related deterioration. I checked it during the photography and didn't notice any significant scratches or missing parts, but this is just my personal assessment, and there may be overlooked dirt or scratches on parts that rub against each other. Please understand that this is a used item that has been opened before purchasing. Please purchase only if you understand that this is a privately stored item. Please be sure to ask any questions you may have before purchasing. Also, to prevent swapping, returns and exchanges are not possible after purchase. Shipping may not be possible if the weather in the shipping area is bad. Thank you for your understanding.
