Finnish Hakaristi roundels, for aircraft from 1918 through to 1944.

These decals are scaled to represent 24", 30", 36" and 48" diameter roundels in 1/600 scale. The actual diameters are 1mm, 1.25mm, 1.5mm and 2mm, so these are small decals....

Obligatory disclaimer; please note that the Hakaristi is not a swastika, and has nothing to do with Nazis; it was on Finnish planes at least a decade before them.
