K9 German Shepherd Clear Vinyl Decal Sticker for Window, Police Dog Warning Guard Sign Art Print

Sticker is approximately 6.8 in. (width) by 4.2 in. (height). The sticker features an all white (ultra bright) detailed monochome style photo and text embedded into machine die cut clear vinyl. This sticker is designed to look best at a short distance (about 1 1/2 - 2 feet from the window). All designs are Copyright Vinyl Designs, LLC.
This isn’t your average vinyl sticker and definitely not a cheap paper sticker. It’s thicker and stonger than most. The photographic monochrome design and text are completely scratch proof. During the manufacturing process each sticker is fused with a special protective layer that protects it from all outdoor conditions including scratches, water, dirt, grease, oil, sun rays, etc. This will likely be the best quality sticker you've ever owned. Satisfaction is guaranteed.
Sticker is MADE IN THE USA from high performance 3-5 year outdoor UV/waterproof clear vinyl. It's made out of the same professional grade clear vinyl that sign and graphics businesses use for outdoor/all weather signage. It will last for years without peeling or fading.
This sticker has a background but it's clear vinyl. Step 3-4 feet back from the sticker and the background is almost completely invisible. There's no possible way to create a sticker with this much photographic detail without having a clear background sorrounding it.
Sticker is easy to apply. It comes with detailed installation instructions. Essentially all you need to do is peel and stick!
