However, please note that I have not confirmed any other operations. Everything in the photos is included, and it comes with a case. As shown in the fourth photo, there are stickers with the previous owner's name on them. Also, a name sticker was originally on the case, but it has come off, leaving tape residue and a slight stickiness (see photo 6). This is a used item, so there are some stains and scratches.
