how to Avoid dust and scratches on my laptop

Hello guys,

I have this LG gram 15" laptop in gold color.
I wanted to know what's the best way to avoid scratches on the top.
Will it be better to use a laptop sleeve or put a skin.

IF i put a skin on the top, i think my laptop would not look good.
So would it be better to use a sleeve and put it in my bag.

Now coming to the screen, due to dust and fingerprints my screen
is not looking good and cleaning it very often is a very big task.

So whats the best screen protector for a laptop.

Thanks.

 

Microfiber cloth to wipe the dust off the screen

 

please suggest for top cover or laptop sleeve

 

Oh, good suggestions!
