These mats ended up being absolutely perfect for my halloween costume. I ordered 12 and got a great deal. It covered my entire costume and I still have one mat left that I will most likely be using for decor. They are very lightweight and the adhesive was pretty strong on it's own. I also used hot glue/tacky glue only for extra reinforcement on my costume. Very easy to separate if needed. I sliced the rows into strips for my costume.
Not very sharp
Great alternate to real glass mirror tiles
