I think they are the same except the ones on etsy have more layers of outer petals. I made some using one of the sizes on the sizzix tattered florals die by doing that & it's close. The tattered florals die made it look more like a carnation than a rose, so I'm looking to get a die that has rounder edges on the petals. I think the biggest thing I found out when I tried it though, was that my die had 6 petals, and I had to make sure that when I folded the petal in half, that the petals were NOT lined up with eachother, but instead were offset. Once I did that, it worked nicely.
I could be wrong about the flowers, but that's what they look like to me. I love them! Especially looking fuller like the etsy picture!
