Haven't had luck finding a slider case.
So I'm looking at the Sheath by Caudabe...

I like how there's no camera bump, unlike their other thin cases.
The Sheath is nice! I’m still considering the Lucid Clear. It’s hard to tell from the pics, but I don’t think there is a camera bump. Cases with camera bumps are meh!
