This white retractable card holder features a silver clip on the back and a black Apple logo on the front. The circular case is 30 mm in diameter and the retractable cord is 30 inches long fully extended.
This is among several unique Apple-logo products that were available at “The Company Store @ Apple” located in the Infinite Loop Campus (in the 1 Infinite Loop building). When Apple began moving to the Main (“spaceship”) Campus at Apple Park, a new Visitor Center was built near the new campus and The Company Store was closed and replaced by more standard Apple Store.
I have four of these in my collection, two in black and two in white.
