What you should consider when all soaps: leave on absolutely a bit, because the main purpose of a shaving is soften the beard hair by alkaline constituents. The difference between a cheap soap and this English soaps are just the ingredients. This soap contains many natural oils and since only the raw materials for the production are not favorable. I shave about 2 times a week and in my case holds a soap min. Six months. Cans foam is much faster and all costs in the end more than this soap. Foaming with the brush lasts maybe Applying the face for one minute.
I can really recommend to anyone this soap a try. Simply buy a cheap paintbrush in DM (only costs a few euros) and off you go. I think everyone who has tried it once will never attack again can.
The soap can be found here even without the cup as refills. You can grate the soap with a normal kitchen slicer small and transfer to another vessel and then melt in the oven ... so could save still costs money that the crucible.
