I'm certain you have not seen one of these bags and you may never see one again once this listing is complete.  This is for the Onitsuka Tiger duffle / weekender / gym bag.  It is definitely vintage and extremely rare.  It is brand new / unused and comes with original plastic wrap.    

You can see from the images, especially the bottom of the bag that it's unused.   

It measures 9in x 10in x 19in

This item is brand new and virtually impossibe to find.  If you want something unique that even your super rich friend cannot get their hands on, this bag is it!
