The article of description. I chose this one when there was orange and cheaper, because it is more transparent than those orange. It ranged from 0.5 mm 0.5 mm 1 mm to 10 mm, then 1 mm in 1 mm to 36 mm. The inside of the circles is beveled, which allows positioning the mine straight into the circle and observe best size by plotting. There is a graduated circle in degree and another percentage. The circles of the same row are aligned with respect to their center. All circles in a square are the centers of the sides are marked with a dash. The dash is very useful for centering a circle to another if one has previously drawn lines in the sense dashes through the center of the circle. Very useful in my case to paint with airbrush roundels on air models.
