It looks like she is using Shiva Artist's Paintstiks, but there are many other brands. Sennelier also makes oil paint sticks in an iridescent color variety like the Shiva ones (and they cost quite a bit less than Shiva's), but you can find a number of different oil pastels by searching on the internet. One place with great prices is CheapJoes.com. No affiliation, just been researching paint sticks lately. As to the permanence, I believe you can heat set the color with an iron (use parchment paper under the project and between the project and the iron to protect the iron and ironing surface) or just let your project sit undisturbed for at least 48 hours. Hope that helps!
