Question about Samsung Galaxy Tab A

I have a Samsung cover for this tablet, which only covers the front and back. It protects against scratches and gives a secure hold. It is magnetic and sticks well to the tablet and allows it to be placed in different positions.

I don't know exactly, but the 'protective cases' from Otterbox are partly dust-proof, sealed all around. Could fit... if Otterbox has a suitable cover for this tab in its range.
