I wanted to wear a pair of elf ears while sitting at the table playing dungeons and dragons with my friends without having to fiddle with alcohol gum or anything like that is another type of glue. These meet my criteria. Just put it behind your ears. They won't stay with you walking around a Renaissance carnival, but for me just sitting at the table they fit. I wish they looked a little more convincing. There is definitely a real ear/fake ear line behind it here, but if you cover it with hair it's ok.
