The SOL is a non-reflective or Reflective decal sticker that is available in three different colors, red, white and white reflective. The decal measures 4.6" and is printed on clear vinyl to give the impression of a vinyl cut decal without having to bother with vinyl masks and mask removal. Printed decals will last longer because they will not fall apart when washed. The red version should be selected if you have clear windows and the white and Reflective version should be selected if you have tinted windows. Under normal conditions, this decal should last 5 to 7 years.
