Most of the moustaches are self-adhesive as they come with a specific 3M medical plaster attached to their backside. The adhesive material is anti-allergic and effective for a long time in high-quality plaster moustaches. It is effortless to attach a plaster moustache to your upper lip. Although, you have to opt for a high-quality one so that it does not come out in between your play or something and leave you in embarrassment at the end of the day.
