These fangs are pretty straightforward. My husband has had these before, but he watched the how-to video on the vampfangs website just to make sure. You mix the stuff, you put the fangs on, you wait 5 minutes, boom, you have fangs. The color matches his teeth very closely and you almost can't even tell. He made sure to tell me how horrible the mixing compound tastes while it's setting. He described it as tasting like melted plastic. What do you expect though? They fit tight and they look great! He's satisfied, I'm satisfied. So sexy.
