Mermaid Decals & Stickers We offer custom window decals for cars, trucks, boats, walls, and most other smooth surfaces. Using our online design tools, you can create a custom logo for your business, sports team, or band, or even upload your own artwork. Our decals are contour-cut to the specific shape of the design with no minimum order requirements. Please note that these decals have no background; only the graphics and lettering will remain once applied. If you are applying a decal to a vehicles glass, we recommend choosing lighter colors for the best visibility against the dark appearance of the windows. Each decal includes transfer tape to hold the design together as a single piece for easy installation. This tape allows you to use a squeegee or credit card to secure the decal and remove bubbles without touching the graphic directly. Once the adhesive side is applied to the surface, the transfer tape is simply peeled away.
