Wasn't 258 shaves the number you got with the Arko? Or am I off on that? Good luck on the experiment! I'll watch with interest.
This soap seems to dissolve a bit faster than Arko when applying. The skin feel is really good. Very barbershop smell.
Considering what Chris says about it dissolving faster, and Perry has experience with it I'm sure he's closer to the number of shaves. But for the sake of competitiveness, I'll stay with 120 shaves. I'm in this for the knowledge.
You're probably closer than I'll be! Chris seems to be able to use these shave sticks in a miserly fashion. My prediction is probably way off.
