Phone that smells when they call you
Such a shocking phone could not have a name other than Keitai Kunkun.
Or rather, it has the accessory that is incorporated so that when someone calls, you do not go through the shame that that horrible music from a television program sounds or vibrates like a man possessed and you have to run to reach it before that falls off the table.
It is an addition that what it does is give off a strong, not unpleasant, odor, for about five seconds so that you realize that someone is calling you.
The tank when the fragrance runs out can be recharged, and I imagine you can do it with the smell you want, to make it much more personal than with a polythene.
