I purchased this on Mercari and used it for about 3 months. The previous owner's usage period is unknown, but there were no noticeable scratches or stains. This is a wireless Apex Pro Mini, but the wireless dongle and Type-C cable are not included. Only the main unit is included. I used it connected to a non-genuine Type-C cable. I will wrap it in bubble wrap for shipping. There are no particular problems with its use.
