Totally sold to Marcel's bars ;-)
* completely zero waste
* very nice scents: this one has the wonderful combination of argan and oud.
* 1 bar is approximately equal to 3 bottles, so very economical
* cheaper than plastic bottles
* sulphate free
With this combination of argan and oud you end up in your shower or bath in a fairy tale of a thousand and one nights.
I really can't think of any cons to these body bars.
