These filigree water decals are from Born Pretty Store, there are three filigree strips and two more floral strips. You can find the latest nail art products from them here and the most popular ones from them here. I have a tutorial on how to apply water decals here. These are versatile as they aren't single images, and you can use them in a couple of different ways. They are a lot easier to use than I originally had expected as well, so even if you aren't good at freehand nail art then these are a good option for something more complex looking.
You can see some of the nail art designs I have used these water decals in here:
