These were brought for a group of grown men to use with zombie costumes. They come with a good selection of designs but are really for top or bottom teeth only, not both. They are made of reasonably durable material and aren't too uncomfortable to wear, if you have a large set of gnashers however they may not fit too well. My only critisism is that they are glaringly white, they had to be distressed with red nail varnish and black and green khol pencils before they started to look real. Saying that though, I would buy again! hope this was helpful.
