Just picked up my first lithops from the local nursery today!

I really hope I don't kill it!

Do yall have any suggestions on what I could add to my mix when I replant? I have cactus soil and perlite, but I really don't want to go the 90% perlite route since it's so light and flies everywhere if you so much as sneeze in its direction 😂 but I don't want to get a bunch more ingredients for a tiny little pot, so I'm hoping one more ingredient will do, but which one? Leaning towards sand or pumice I think but I'm just not sure 😅

TIA!
