I purchased this several years ago, but I never used it and have kept it in storage. Therefore, there are some dents and small tears on the outer box. I have never used it, so I cannot explain the usage in detail. Everything included is shown in the images. The sizes listed in the instruction manual are as follows: ● Cutting height attachments: 3mm/6mm/9mm/12mm ● Precision hair cutter guide comb: 4mm/4.5mm/5mm/5.5mm
