I decided to get the 12 samples because I am sensitive to fragrances and often find that when I go to buy colognes, that they give me a headache. So far I have worn two of the scents and have had no reaction to them. They are light smelling, so will need to reapply, but I don’t see that as being a flaw. Look forward to choosing one or two to be my main fragrances in the near future.
