The Magic Sleeve extra small (accessories) is 11.5 x 8.75" unfolded. It's great for power cables, pencils, pens, and power bricks. It's been designed to magnet to the exterior of any other Magic Sleeve while on the go. It hangs onto the edge of your main desk pad while at your home base. Or it works well as a bedside charging pad that converts to a travel sleeve for cables and power adapters.
