A Closer Look
The Nobility N702 has a metal casing. It is not completely straight, but has diagonal folds which does give it that jewelry look. The black part is made of plastic and A-Data has chosen to print the company logo on the side, so it does not disturb the overall look of the device.
To extend the USB connector, you simply twist the black part of the flash drive 180 degrees. The connector itself is missing the metal enclosure, so you may plug it into your USB port upside down. Even if you do, that does not harm the N702 or the plug on your computer.
The two strings can easily be attached by sliding the metal ends into the groves of the black plastic part. Both hold quite well and seem to be sturdy enough. So you will not have to worry about them ripping apart.
