Hard cases for tablet

Smallclone

Hi,

I require 2 x tablets for the kids. Ideally 7 inch ones. However, they need hard rubber cases on them. Like this:

Tab A 7.0 Inches Armor Case DWaybox 2in1 Combo Hybrid: Amazon.co.uk: Electronics

The only rubber cases I can find on amazon and ebay are specifically for kindle fire and samsung tablets (which I don't really want to buy).

I was hoping to buy a Lenovo Tab 3 A7 - would any hard case fit this tablet?

Thanks
