This is the original-equipment (OEM) Subaru badge that goes on the trunk of the limited edition WRX STI Type RA. You get the red STi logo, plus the Type RA special chrome bits, all pre-placed in a nice foam positioning template (intended for the trunk of a 2015+ WRX or STI, but you could always stick it on anything).
If you already have an STI, you'll have an extra STI badge you can stick on your tool box, or give to a friend.
About 4" wide by 3" tall. Peel-and-stick installation.
