ALooks like the blossom art petunia cutter and veiner to me.
AIt's definitely not royal icing. When you use a veiner it thins the flower and gives it movement.
ok, this is ridiculous. The pic is there when I "preview" my post and appears to be successfully pasted in, but disappears when I hit submit.. very odd. Here is the link to the set: blossom set (SV-005). GSA says it's out of stock, but at least you can see the pic. It is also avail from other sources on the web (I did a search).

As already posted, it's a simple cutter and veiner and the flowers are gum paste.
The cutter used in the Global Sugar Art link will give a more rounded flower... the cutter in the OP's pic are petunias (as cupcakemaker has said).
Here's a link to some that I did a while ago...
