One of my passions is old, classic, veteran and vintage motor cycles. This is my version of a vintage sized sparking plug, but one with a difference. Pull off the 'threaded' portion and it reveals a USB connector.
Hidden within is a 4GB memory stick, jump drive, flash drive, flash disc or memory key. It's made from English yew.
The memory stick measures about 3.5" x 1 1/8" dia and is fitted with a fabric lanyard. The tins and real spark plugs in the photographs are, of course, not included.
