There are many stickers and decals to choose from so it depends on what you are using it for and what do you want to put it on. There are decals that are have high adhesive (they can be used for semi permanent use), low adhesive (removable if removed within a short time) and no adhesives that are considered static clings. Once you figure out how 'sticky' you want your sticker to be, you then have to decide whether you want your decal to have a background color or did you prefer a clear background. Standard decals, Removable decals and White Static Clings all have a white background on the decals any place that your artwork is not covering. Clear decals and clear static clings both have clear (transparent) background options. The options include spot white and flood white. Almost all of the decals and stickers have three Special Cut options: Circle, Halo and Oval. The Standard decal offers a 4th Special Cut option called Exact Cut.
