Sleeve for iPad Pro w/ Magic Keyboard

I’m having a hard time finding the right sleeve for a new iPad Pro 12.9 with Magic Keyboard. I’m looking for something that is slightly padded, completely enclosed (so I can carry it in another bag without letting dust and debris inside), and preferably with a dedicated, safe Apple Pencil holder. Everything I’ve found with these features lists internal dimensions that are either too small or too big for the Magic Keyboard. Any suggestions would be appreciated!
