I am aware of Vitos, Cella, and TFS. Maybe Arko if you count the 15 stick package. Any others?
I am sure that @BigAlVista can whip you together a single 1 kg block of soap. Well I can do that also....Seems like Europeans have more options than me. I can't easily find a place to buy most of these suggestions. Ah, well. I have a kilo of TFS coming to me courtesy of my friends at Italian Barber.
I want to give some quality soap to a friend moving to remote Alaska. He won't be able to shop regularly for personal supplies and the cold climate I think would help preserve the soap if he stores it in a dry place.A kilo of soap is a huge commitment, in daily use you could be talking about 4 or 5 years of daily shaves. You'll need to store it properly, so break it into maybe 5 chunks, vacuum seal it and put whatever you aren't using in the freezer.
To put it into perspective here in Ireland you could get less time for armed robbery.
