This is a Personalized Perforated vinyl rear window decal for doTERRA Consultants. The sizes are 20 inches wide by 12 inches tall and the larger size of 30 inches wide by 18 inches tall. The perforated adhesive vinyl allows you to see out the back window while potential customers behind you will see your decal. Since it is an oval it is very easy for you to apply and much less complicated than the full window decals which takes experience to make them fit perfectly. Best part is it has YOUR Name, YOUR Email and YOUR Phone number. Great advertising Potential!
