The Dux Plus Duo has been tested to exceed U.S. Mil-Spec drop tests and withstands the tough conditions of classrooms, workplaces, and everyday use. The case was developed in collaboration with educators and IT professionals and features a magnetic closure, a transparent back for asset labeling or user customization, and an integrated compartment for the Apple Pencil or Logitech Crayon. It is made from super protective polycarbonate and a rubberized holder. The clear back allows for personalizing your device, scanning a barcode tag, or showing off your pristine device. The durable and waterproof polyurethane cover protects against occasional drops or spills. The patented magnetic closure allows for easy opening for typing or viewing. The cover also automatically turns the device on and off to conserve battery life. It provides additional storage for pens.
