I purchased this in February 2023 at my father's request, and it is in like-new condition. There is a paper with the serial number. I have not registered as a user. Also, please understand that the product will be packaged simply. The basic packaging will be bubble wrap + plastic wrap for water protection + wrapping with craft paper. I will consider price negotiations, but it will be based on the premise that shipping costs can be reduced by considering the shipping method.
