These decals are meant to be used with the Revell 1/24 scale Gemini kit. They include UNITED STATES and US flag markings, thermal stripes for the adaptor section, red markings on the nose section, NO STEP markings for the doors, and more. All colors are in perfect registration on my sample, even on the US flags. The decals are identified by numbers on the sheet that are called out on the instruction sheet. You'll have to decide which mission you are modeling before you apply the markings: earlier missions had thermal stripes on the adaptor section, while later missions used smaller squares. Two different markings are given the same number on the sheet, but there shouldn't be much confusion: the NO STEP markings won't be easily confused with the thermal squares (they are both given the number 13).
