Thank you for viewing. This is my first time selling, but I will handle everything with care. Thank you for your understanding. I only used it for testing, and it has been stored in a closet since then. I have confirmed that it works, and the box and other accessories are included. I am selling it because I don't use it. Please consider purchasing if you understand that it is a used item.
