Here is how I have the soap samplers set out at market. On the back of each business card is written all the fragrances of the soaps inside that gift box. They are selling very well, as many people buy them for hostess gifts, little soaps for the gym or traveling or just to try some of my soaps.
Soap Samplers are available only at market and only by chance. They sell quickly! (but you can send me an email or give me a call, I know the gal that makes these up and she would be happy to help you get your hands on one or two).
