Bests & Worsts Reviews from Amazon

I bought two packs of these (20 5"x9" sheets) from which to cut triangles to decorate a blazer to achieve a broken-mirror/disco-ball effect (this ended up being just enough to cover an entire M/L jacket). They are made from a thin plastic material and the mirror image on them is surprisingly good. They ship with a protective coating on the mirror side which needs to be removed. The material cut relatively easily, but the edges tended to crack a bit from the pressure of the scissors. I was prepared to hot-glue them to the blazer but the adhesive worked well enough on its own (I wore the costume throughout the day and the only pieces that fell off did so because of how I applied them to the bendy areas like the elbows). Overall, I can highly recommend this product for similar crafting purposes.
