Product life will vary with material choice and lamination type. The ink has a quoted lifespan of 3+ years (without lamination), and the vinyl is rated for 3-5 years. Our lamination doubles the lifespan by adding another clear layer over your image. Keep in mind that some materials, such as metallics, have lifespans as little as 1 year (outside).
You will find that the value you get from vinyl stickers far outweighs many other options.
