The box is severely damaged. There are no instructions, only what is shown in the photos. When the main unit is shaken, there is a rattling sound of 2-3 grains of sand-like material inside. A non-professional has only confirmed that the unit functions normally. Please refrain from purchasing if you are particular about the key feel, etc. Not all scratches are shown. Please be aware that there are scratches overall. I have wiped it clean, but there are some dirt stains in the crevices that I couldn't remove. I have another item for sale, but I will not combine shipping if you purchase them separately. If you purchase them together, I can only reduce the shipping cost to 750 yen (limited to the campaign period).
