Yes I've seen it at walmart too and some others stores online....
It is a mexican product, like of course Zote soap bars
In Mexico and latin countries it is still usual to wash with soap flakes, in machines also....
Some brands I recall are: Lavador and Candado...
I used to grate my own soaps....
In Italy there are available soap flakes forms too, like Spuma di Sciampagna and Chante Clair....
