The device consists of a charging cable which can be tidily wound round a circular holder and a SIM ejector. SIM cards must be changed above all by users of smartphones with dual SIM and for travel abroad. The ejector necessary for this is stored safely and is at hand at any time. The pleasantly flexible charging cables are rolled around the flat holder and fixed in place. The 360 Cable Carrier N4 is available in contrasting colours of silver and black or black and red.
