...we have my 3D flowers. I have no idea what they are made of, I purchased all of them from Ebay. They're easy to use. I personally put a bit of nail glue on the area I want the flower, use tweezers to pick the flower up and place it on the spot you want it. Use the tweezers to hold the flower in place foe a couple of seconds, and boom! you're done. These are very pretty, and create a really nice look.
