The purpose of stickers is to cover something or it is used by companies to carry their product details and the logo of the company on it. Some of these stickers are of permanent nature and cannot be taken off unless brute force is deployed while some stickers are temporary.
These are temporary and can be easily taken off. However, there are still some stickers that are neither temporary nor permanent. These are rather more of an irritating formality by the company. These stickers leave their mark behind in an attempt to remove them and make the product look ugly just like in the picture shown above.
