First and foremost... I hate the ever loving shit out of those foam fintie cases. Holy shit are they terrible. For users they're probably great but if you have to put that case on and take it off it's the biggest pain in the ass.

We use cases similar to this https://www.amazon.com/Generation-Shockproof-A2197-A2198-A2200/dp/B0819JSXTR/ref=sr_1_15?dchild=1&keywords=ipad+case+with+kickstand&qid=1602638836&sr=8-15

without the loud colors. We buy a very basic grey/black combo. So far no problems and we've been doing these cases for about 3 years now but this is the first year of 1:1.... which is oddly enough less ipads then we had in productions prior to.
