I purchased these for a spy birthday party for little ones.  They wore these and black sunglasses.  The pictures are absolutely delightful.  The kids had such a good time putting these on.  I was suprised at how well they sticked.  I would say they are a bit itchy on your face, but really how long are you going to wear them.  I have very sensitive skin and once I removed it I thought my skin might turn red but I had no problems.  The mustaches are in small packages of 4 or 5 (can't quite remember).  You could easily cut them apart on the backing to give to individuals.  I think the price was great for how many there were.  Loads of fun!
