Warbird Decals is known for its aircraft decal line, and now it is making new strides into real space subjects.
Upon opening the ziplock bag, you find two letter-size decal sheets which includes lower surfaces and upper surface/rudder tiles, and one single page with a 4-view drawing of the Space Shuttle with a decal map. The decal sheets provide extra decals, but the instructions do not tell you what for (more on this later).
I built the Tamiya Space Shuttle a few years back. You can find a review of the kit at http://web.ipmsusa3.org/content/space-shuttle-atlantis. It is a nice kit, but certainly has room for improvement, mainly due to the lack of tile detail in the lower surfaces.
These decals are very glossy and conformed to the surface perfectly, without needing to use any decal solution. They were easy to move around for good alignment, too.
