They are Soul Source GRS vaginal dilators. I didn't get them in an box, so I have no idea about that part, but if they're not Soul Source, they're the wrong ones - and if they are, they're the right ones, because Soul Source only makes one set. Brassard now issues the three largest dilators only (blue, green, and orange). Incidentally, since he only requires three of the set of six, the total price on the Soul Source site itself is roughly $150.
However, the dilators were included in the price for me as a private-pay patient; I didn't pay a single penny more to get them. So I would *definitely* recommend that you verify with the Alberta health services and the clinic whether it is covered. (I was there with two girls who had their GRS covered by Canadian health services, and the dilators were included, but I'm afraid I don't recall which province(s) paid for those two girls.)
Edit to add: I've been told it's OK to link to this one specific site to aid in GRS planning, so here you go.
