Smartphones Cover - which material?

I need to print covers for devices (similar to smartphones) that can accidentally fall down and crash on the floor.

Which Z-material should I use? And why?

For black or White objects? And for coloured ones?

Thank you ;)

I vote for Z-Ultrat.

I haven't used HIPS, but I'd probably use ABS since it's the most flexible.
