The teeth are nice and the principle too. As against it have never kept. Maybe I did not quite expected the glue sets? The adhesive is in a small plastic bag and it is very difficult to extract enough. Moreover, I am perhaps not good, I found myself with lipstick full teeth, I find them a little too big so he is very difficult to make up with. In conclusion I was not dressed as a vampire for Halloween this year, Fortunately I had planned something else. If delivery is fast.
