These are the next size up from 100mm cigarettes and are usually the lengthiest commercially produced cigarette available on the market. The big variation in this size cigarette is in the diameter. In most cases, these cigarettes have a smaller diameter creating them appear 'slim'. Lots of people are under the assumption that because it is longer, is has a lot more tobacco and this is typically not the case. Once more, this can mostly rely on the producer, but these will have just about the identical quantity of tobacco in it as a 100's cigarette. It just seems a lot thinner and longer.
