Thank you for viewing! This is a USB-powered, interchangeable-tip electric grinder/cutter, useful for making small items like plastic models and accessories. The rotation speed can be adjusted steplessly by turning the knob. A power cable is included, but a USB power adapter is not. The box has been opened to check the contents, but the main unit and bits are unused. Please check the condition in the images. Thanks to opening the box, I discovered something interesting (laughs → see image 6, yellow circle). What is shown in the first image is everything that will be sent; the manual is not included. It will be delivered via Yu-Packet Post Mini. If payment is completed in the morning, it will be posted on the same day, or at the latest, the next morning. Thank you. #kokky
