Decals are decorative stickers or designs that can be applied to various surfaces, such as walls, vehicles, or windows. They are made from materials like vinyl or paper and often feature colorful graphics or text. Decals can be used for personal expression, branding, or advertising purposes. Applying a decal is usually straightforward; the surface must be clean and dry, and the decal is pressed onto it, often using a transfer tape. Once in place, decals can be removed or repositioned without damaging the underlying surface, making them a popular choice for temporary decorations or promotions.
