mumbi Retractable Cable USB 2.0 Type A to Micro-B 90 degree angle plug

The USB cable is working properly. We now have three pieces of it to load with the appropriate charger mobile phones; one of them for three months in daily use. They take up less space and can also be great in a drawer store without there mess, as in rigid standard cables. However, a small manual is missing: Always hold both ends and pull out! It can then lock in about 8 positions. In principle, like a spring or snap-blind at the window. To curl: short pull on both ends and it rolls on. Total length about 70 cm
