Don't judge a book by its cover.
Twelve South makes a ton of high-quality accessories for Apple devices, and its BookBook case is no exception. These cases are designed to not only protect your iPad Pro while it's not in use but also while it is in use.
Each case has a safe place to store your Apple Pencil while it's not in use. The inside is lined with a felt material to prevent scratches and abrasions, and the case actually fully zips so that nothing will get inside of it while you have it in another bag.
