the inside where it slides in is a soft felt and the inside cover is a soft felt. The cover really never touches the screen. I've had the same case on my kindle from last year and never had an issue with scratching. My screen is completely scratch free. You can buy a screen protector as an option though.
It is well protected when closed, there is no plastic protective covering for the screen itself but I find I have not needed one. I am careful to use clean hands. I would not personally use a screen protector.
no there is nothing for the screen I ordered that separately. I do like the cover a lot. It s really nice for the price. If you keep the cover flap on it when not in use the kindle is protected. GEt a stylus for use protection.
There isn't one included with the case, no. As other have said, it's pretty well protected from bumps and stuff, but if you want to protect agains dirty fingers or whatever, you'll need to buy a separate screen protector.
