Minimal protection found here

Even though you want to enjoy the in-hand feel of your Galaxy S9 or S9+, it's still a good idea to protect your investment with at least a thin case. Your best option is the Spigen Thin Fit, since it offers the best balance between protection and a slim profile.

But if you want something with an even lower profile, then you'll want to check out the Totallee Thin Case. This case measures in at just 0.02 inches for an ultra-slim and lightweight case while feeling premium. You won't get the most protection here, but there is enough to at least help in the event of a drop.

If you decide you want something with a bit more protection, or a case with an extra feature like a kickstand, there are plenty of other cases on the market for the Galaxy S9 and S9+ out there for you.
