The image shows a set of four gray plastic wheels arranged in a horizontal line on a blue cutting mat. The wheels appear to be made of plastic and have a round shape with a small hole in the center. They are arranged in two rows of three, with the largest wheel on the left and two smaller ones on the right. A metal tool, possibly a screwdriver, is resting on the mat next to the wheels. The background of the image is a grid-like pattern.
