I can't check because I left my leather sleeve on an airplane years ago. But I'd be shocked if it were a good fit-- that thing was so tight with just the original keyboard on the 2017. The MK folio is so much thicker!
Would you mind sharing some photos showing how it really looks like?I just tried and I got worried that it might break the Magic Keyboard. Thickness does not seem to be an issue. The iPad with the MK is too wide though. You would really need to force it in there. Maybe after some stretching the leather, but even then I would think that it is not comfortable to use.
I cannot imagine that it doesn't look tight. 😅Would you mind sharing some photos showing how it really looks like?
