I ordered these last minute for the 100th day of school. My daughter's wore the mustaches to the store they stuck the whole day. My son's wore theirs to school. I cut some of the mustaches in half to use as eye brows. They had extras to put on in case they came off from lunch or sweating. They didn't pull their hair out on removal, the adhesive was very effective, they looked hilarious both my sons and daughters made people smile and laugh. The mustaches did exactly what they were meant to do. I was worried they wouldn't stick well as most do not but these held up and the boys were able to eat with them on.
