I ordered these fangs as the finishing touch to my Vamipress Halloween costume, however, I wish I had spent the extra money to buy a different type. The compund used to fit and hold these onto your teeth is practically useless. The fangs will not stay on my teeth at all. I ended up having to buy another product just to hold them on. It is also difficult to talk with them in, but that's something that would be expected with almost anything that goes on top of your teeth. I would love them if I could get them to stay on my teeth the way they are supposed to.
