I don't think they exist yet. And they might not ever, as I believe they are into the 4th generation ceramic cartos now. The CE2s were a nice idea, but a pain in terms of maintenance, filling and just keeping it
vaping well. But the bottom line is I have not seen them. Vendors do make their own clearomizers, but the coil assembly is original CE2.
If another vet knows differently, my post can be deleted.
