A sticker is a type of label: a piece of printed paper with a pressure sensitive adhesive on one side. They can be used for decoration or for functional purposes, depending on the situation.Stickers can come in many different shapes and sizes and also vary widely in colour and design. They often adhere to items such as lunchboxes, paper, lockers, notebooks, walls, cars, windows, and so on. Stickers are very widely used when an object requires a word or idea.
Brand stickers may be attached to products to label these products as coming from a certain company. They may also be used to describe characteristics of the products that would not be obvious from simple examination.
