Please customize with the wording you'd like for your sticker. There is a limit of 16 characters for each decal. The letters will be constrained by either a length of 10 inches or a height of 4 inches. So, two letters will be 4 inches tall and the length of the characters. A word or words that have 16 characters will be 10 inches long and approximately 1.5 inches tall depending on the font chosen. There are several fonts and colors to choose from. Please be aware that some hard plastics will resist adhesive vinyl, so this material is best for glass and glossy painted surfaces.
