Cigarette ashtray..
Maybe some of us are not aware of the importance of cigarette ashtrays, in addition to keeping the cleanliness of cigarette ash was there that is more important and useful in my opinion .. while smoking our cigarettes often even always hold a cigarette that should be put in the ashtray do not continue to hold the cigarette that we have burned it smoke from both ends let alone choline cigarette was wet when sucked .. in expecting not to always hold a cigarette while smoking ..
