This post is all about the curls; Curly Plants and suggests a few other possibilities.
I would suggest that it may not be quite as drought tolerant as most succulents, so water carefully, and if it is a bulb, remember that the bulb part is water storing, and will rot easily if kept too wet.
Sorry I can't be more precise, this is one plant I haven't come across before!

I guess I have to poke in and see if there's a bulb. I had only seen similar plants online until yesterday, so when I saw it, I had to get it. As usual, all the label said was "assorted succulent"

It’s called Albuca spiralis by: Feel Good Planters
It’s an Albuca Spiralis. It is a South African protected species and very rare. Loves warm temps and is not cold hardy below 30 F. Better to pot so it can be brought inside during colder months. Blooms from spring through summer. The blooms are fragrant. If you reply make sure the top of the bulb is uncovered. It likes a bit more water during blooming season.
