The difference between a sticker and a decal
A sticker generally refers to a piece of paper, plastic, or vinyl with an adhesive backing that can be attached to a surface. Stickers are often used for decoration, labeling, or promotion of a particular product, brand, or event.
A decal, on the other hand, is a design or image that is printed on a piece of paper, plastic, or vinyl and then transferred to a surface using a transfer film or water-soluble adhesive. Decals are often larger than stickers and can be used for branding, advertising, or to add custom designs to products or vehicles.
In summary, stickers are usually smaller and have a sticky back while decals are larger and are often transferred to a surface through a transfer process.
