These are GM licensed decals perfect for use inside or outside. Made of the highest quaility 3M material. Each decal is UV protected and guaranteed not to yellow or color fade for up to 10 years. We hate to call them decals, because they are more like a hard emblem then a decal. We bring them to every Corvette show we vend, and we sell out of them every time!!! Vette owners are just amazed by the quality of the graphics and the fact that they just look so much better then the cheap looking flat vinyl decals everyone else sells. Plus to top it off they are available in many of the Corvette colors. Don't get stuck with some cheap flat vinyl decal that peals up and fades after a few months or doesn't even make it through the installation.
