Protect the back of my Air3 with Smart Keyboard

Help?!

I purchased a brand new Ipad Air 3, along with a Smart Keyboard and Pencil 1st gen. I love the keyboard, however it leaves the back of my iPad bare, with no protection against scratches, etc. Is there a cover for the back that will work along with the Smart Keyboard? Maybe something to hold the Pencil too?
