If you don't mind ordering from Canada, it looks like the Chapters site finally updated the KT covers and sleeves. Just scroll down past the KTs on this page and you'll see them on this and on the 2nd page. The covers on the 1st page will flip open like a book, and have elastic corner straps to hold the KT.
