WWII Italian roundels with the fasces design but no background. These were sometimes used as a less conspicuous alternative to the usual markings. Note that this sheet includes both left and right sided decals, although the small size means that they are of necessity somewhat stylised.
These decals are scaled to represent 30", 36" and 48" diameter roundels in 1/600 scale. The actual diameters are approximately 1.25mm, 1.5mm and 2mm.
