Cella is a magnificent soap! As a matter of fact it has been my replacement soap when they quit making the super glorious P.160.
Add to this it has the classic Italian almond scent - although as not intense as other Italians - it makes a good soap for the ones loving this scent, including me, of course.
Very easy to mount, it gives a luxurious lather in few seconds. As for keeping, it virtually lasts forever, in particular if you keep it in the refrigerator, something I do with all of my soaps.
The 1kg pack is bargain: its price, here in Italy, is about 10 euros.
