Soviet red stars with a white border. Most Soviet aircraft used this style of marking, whether the aircraft was camouflaged or in a natural metal finish. The main alternative was a yellow border instead of the white, plain red being unusual.
These decals are scaled to represent 30", 36" and 48" height markings in 1/300 scale. The actual dimensions are approximately 2.5mm, 3mm and 4mm. While primarily intended for 1/300 scale fighters, they're also ideal for heavy bombers in 1/600, and even for use on larger scale vehicles.
