Was going to a themed party that I had heard of 3 days ahead of time so clearly not enough time to grow a nice, thick 'stache. Bought these from Amazon, came in one day. A few hairs will randomly come off and might get in your drink(s) so wipe it with your finger before using to get any loose ones off. The adhesive is good enough for it to stay on, even when laughing. I'm 22 years old and this was still hilarious.
