Have you seen the wonderful shape that catches your eyes when you are in Wal-mart or any grocery store? Many people are smokers, and most of them know about the damage to health by smoke and cigarettes. But the companies of cigarettes don't care about people even though they put warnings outside of packets "Surgeon General's Warning: Smoking by pregnant women may result in fetal injury, premature birth and low birth weight" and the companies of cigarettes just need to increase them benefits, and they try to make unique shapes and attractive colors for packets of cigarettes to make the shape more luxurious for consumers. 

If you are smoker or not, you would like to see something attractive and you would wish to have it. As I'm a smoker and I have my own loyalty to Marlboro Company, but I like Davidoff's cigarette design and color; its reddish brown color, and has a bevel shape on both sides, that make the packet seem more "classic" than other kinds of cigarette packets.

A packet of cigarettes rectanglular shape has been designed and packaged in order to fit the pockets, so that the smoker feels more comfortable of the size of the packet if it wants to put in his pocket, usually made of cardboard and light-weight at the same time is easy to get to the client. A packet of cigarettes usually consists of two main parts:(a) Cover and (b)Caddy of cigarettes. Cover: It was designed in an elegant suit with a whole box and it was designed this way specifically to be easy to open and is more appropriate to customer requirements. 
Outer cover of the box is covered with transparent plastic, so that the client can read the writing on the box. For ex: Warnings and production and expiry date clearly, as the cigarette manufacturers insert an expiration date to be more credible with clients, consumers. 
Add to that the clear plastic box which has been developed consisting of two parts: (A)The upper part ,which is removable, covers the outer cover of the box where it is easy to remove, and (B) The sturdy plastic bottom part of the packet. 
The lower part is made to keep the outside of the box from water by accident, and also that the plastic sleeve protects the cigarettes inside from exposure to air or sunlight for too long to protect the cigarettes from moisture.
