iPad Air with Apple Smart Case in Sf bags EXO sleeve in Muzetto bag
They are from Etsy, Come from Japan but the delivery only took around 7 days to me in the UK. You can choose to either have the sleeve to fit just the Air or to fit the Air with the Smart Cover on. I believe if you message the seller they will also make custom changes if there's anything on the sleeve you want changed.
