The SanDisk Ultra comes packaged in a cardboard blister pack. This type of packaging is not only more eco-friendly than the plastic clamshells that most USB flash drives come in, it can be opened by simply cutting along the dotted line.
While not nearly as small as the Cruzer Blade, the SanDisk Ultra is still fairly compact. With the USB connector retracted, the drive measures about 57mm long, 21mm wide and 9mm thick. At this size, the SanDisk Ultra is barely noticeable when carried in a pocket or on a keychain.
The body of the SanDisk Ultra is constructed of a lightweight, black plastic. While the top has a glossy finish, the sides and bottom have a rougher, matte finish which makes it a little easier to hang onto the drive. The SanDisk Ultra also has a hole on the end so that it can be attached to your key ring.
The SanDisk Ultra's bright red USB connector is exposed using a unique sliding mechanism which can be manipulated with just your thumb. Underneath the sliding mechanism is an LED which pulses rapidly when data is being transferred and slows down when the drive is idle.
