This sticker is made from a 6 year outdoor vinyl.  It is a single color die cut decal.    The decal will be only one color.  We usually use white.  It seems to show up best on car windows.  We have other colors of vinyl if you want a different color.  We have White. Black, Orange, Neon yellow, Red Blue white Pink, Light Pink, Purple Lavender, green.  The decal has a clear transfer tape on it, so you can see how you are applying it. Make sure you are applying it to a clean dry surface.  Carefully peel off the backing paper and  apply the sticker to the window.  Make sure all the sticker came off the backing paper and sticks to the transfer tape.  if it doesn't, then firmly press down on it with a squeegee or credit card or something similar until it sticks to the clear transfer tape and then remove the the backing paper.   A credit card will work to squeegee it to the window and work out any bubbles.  Then pull the clear transfer tape off very slowly and carefully making sure it all sticks to the surface to which you are applying it.  Carefully peel the transfer tape making sure the sticker comes off the transfer tape and sticks to the window. 
We cannot accept returns or exchanges on decal stickers.  Sorry, but some surfaces are harder to apply to and some decals, especially the smaller ones are harder to apply.  If I don't hear from you about color, I will send your decal in white.
