Absolutely the best on the market. They're custom, they fit (so long as you follow the EASY instructions) and with proper care, they'll last forever. I wouldn't recommend trying to refit them, as in melting them down over and over and making new molds. The process is easy, and once you're done, you've got the best creature-costume all around! I especially love the fact that you can SPEAK while wearing these, and eat or drink (I'd be weary of colored foods/drinks, just incase.)

Just NEVER leave them out in the open where the sun will get them. ;) Seriously, they melt.

These are the only fangs I'll buy for my costumes.
