The Dammit Boy Fire Dept decal is a non-reflective decal.  The red version is a vinyl cut decal and the white version is a printed decal.  The white version is printed on clear vinyl to give the impression of a vinyl cut decal without the masking material.  The red vinyl cut decals are easy to install.  Just peel off the backing material and place the decal where you want it.  After rubbing over the masked material, then carefully remove the mask and your decal is installed.  The decal measures 4 1/2" tall x 4 1/2" wide and can be printed in a choice of red or white.

The dammit series of decals were originated by The Stickerman as the result of a popular expression used by a volunteer firefighter in Georgia.  It seems that every other word was dammit this and dammit that.  The expression was put on a decal and thus we have the dammit series of decals.
