So, after finding out that Home Depot, of all the places, has leather cases for iPhone 12 variants, I decided to take a chance to order one for my 12 Pro Max. These are ProHT brand and, with Home Depot's generous return policy, it was worth trying. Build-quality is pretty similar to Apple's official leather cases. It does feel a bit more slippery than Apple's version. Leather smell is there but only time will tell if these are real leather. Buttons are a bit tight to push; however, they are pretty good. Fit seems very good, except for a very slight gap at the bottom.
