You know all those school bumper stickers that say, "My child is an honor student at..." or "Proud Parent of Student of the Month at...", well I thought it would be fun to make one for parents of boy wizard fans! This one says, 'Proud Parent of a Prefect". Can't you just imagine this on a Ford Anglia? Each bumper sticker measures 3 x 10 inches and is made of a synthetic material thinner, but stronger than vinyl. Bumper stickers typically last up to 2 years outside in normal weather conditions, and can last up to 7 years if garaged. They are removable with soapy water or Goo Gone.
