The sample helps to inform your choice for future purchases. I realized that I preferred the black detox soap for my face out of all of the soaps. What I will say is that they need to label the soaps so that you know what is what. 4 unlabeled soaps makes it difficult for me to purchase the full size of a bar that I like. I have to guess. Thank goodness the charcoal soap is the only one that is black.
