Operation confirmed. I'm selling this because I've finished it! I've included photos of the back of the disc and the operation check, so please take a look. I will pack it in bubble wrap and ship it. Depending on the item, it may be compressed for shipping. Also, since this is a used item, I have inspected it, but there may be oversights. I appreciate your understanding. If you have any questions, such as the size you're interested in or parts you'd like to see, please feel free to ask ★
