This great looking drive employs a swivel cap that keeps the USB port protected when not in use, but stays attached while transferring files so that it can't be misplaced. The LED light flashes when the device is detected by your computer and stays on while data is transmitted. As with all of our flash drives, the 020 can be customized with the logo or design of your choice. This drive meets required FCC certifications as well as a voluntary RoHS environmental certification.
