Dry erase marker on iPhone 6 Plus?

I have a Gold iPhone 6 Plus and yesterday I got a clear back case for it. As an artist, I thought it would be fun to draw on the back of the phone and do a new little drawing every day, but it's obvious that sharpie wouldn't come off. Can I draw on it with Expo dry erase markers and wipe it off every night?

I hope you know that since it is dry earse the drawings will come off.very easily.
