This 3 in 1 cable organizer can hold both thin and thick cables.The thinner cables snap into the grooves on the outside of the ring just enough, so they can be firmly held together.Cables larger than 3.5 millimeters can be treaded through the insige of the ring.Cables can also be winded up onto the ring for travel.
