You write your geocaching.com tracking number on this tag!
Is your trackable geocoin, Travel Bug®, or other traveling item lost or stolen? Do you want to keep your geocoin in your collection, but still let the tracking number travel the world? Then put that tracking number to good use and keep it traveling by using the DupleBug. No need to by a new coin or tag, just reuse your old tracking number.
When the tag arrives to you, simply write your tracking number on the backside with permanent marker. You can then put this tag into the geocaching wild and continue to see your tracking number travel. It is like recycling those unused numbers, and you can save money by not having to purchase new geocoins or TBs.
This is not a trackable tag by itself. You must supply the tracking number you want written on it to make it trackable.
