These are great little fangs that work well for pretty much any costume. Be aware that they are fairly large and prominent-- I got a sore jaw after wearing them for some time because I couldn't close my mouth completely, but they're easy to snap on and off, even on the go, so it wasn't a major problem to just take them out until I needed them for photos. Fitting can be a bit of a hassle-- I recommend doing it ahead of time-- but once you have them properly secured, they don't need to be re-fitted. I had to use double the amount of adhesive for one side since my tooth was smaller, but that just meant applying it, letting it harden, and then applying the second measure on top of that in order to ensure a good fit. The case they come in can also be used for storage, carrying, so that's nice.
