I currently have two original iPad Air and one Air 2 that are in the leather SmartCases that Apple used to sell. What is the closest thing to that case that I can get for either a 9th gen or 10th gen iPad? I don't want any elastic straps for the cover, no flap holders sewn on, etc.
This is probably the closest I've seen but is only for Pro models.
