Yep! That's a cookie cutter set with some piping on top. Let me see if I can find it...
Google "snowflake cookie cutter set". The second link is the set that I have but the first link looks lovely as well and has more options.
Thanks heaps! Have a wonderful day!
Is the cake you have pictured in the galleries and do you have a link to it?
She sent me a better link:
Beautiful cake, are these cookie cutters sold by Global Sugar Art, I wonder?
