The Magic Sleeve Duo measures 12-1/4" x 28-1/4" when open and flat. It's a new size designed to hold a 13" notebook and a 11" or 12.9" iPad. Work with your devices side by side with sidecar. Or use the extra wide space as a space for a mouse or trackpad. A cable keeper can be added anywhere on the perimeter of sleeve to keep your cables from slipping off the desk pad while your devices are not present.
We are working on the initial units of the Duo and expect to be able to ship them within 2-3 weeks.
