KEEPING hold of your USB drive isn’t always easy; in fact, as with mobile phones, it’s hard not to lose one along the way. Busy people lose track (踪迹) of things. This little device (设备) may be just the solution. It’ll clip (夹住) onto anything you need it to stay attached (附在上面) to, because not only is it a USB, but a clothes pin (衣服夹子) too.
