Before you apply the sticker, first and foremost, clean the surface you'll apply the sticker to

The sticker comes in 3 layers

1. Top, clear layer
2. Middle, sticker layer
3. Bottom, paper wax layer

(If possible, slightly mist the surface with water you want to apply the sticker to. The smaller amount of water, the better.)
To apply the sticker, peel the 3rd, wax layer. Then place the top 2 layers over the surface. (Peel up and reposition if need be.)
Once positioned correctly, use a credit card or grocery store card to scrape out any bubbles.
Finally, remove the top, clear layer, leaving only the vinyl sticker behind.
The sticker is set!!
