Looking for a little drawstring pouch

I’ve seen that some of the Fuze+ shipped with little black pouches with a drawstring top closure. I would really like to get my hands on one of these, if anybody has one they would sell or otherwise know where to get it I would be grateful! Thanks.

My Fuze+ came with a pouch and _ no drawstring_:confounded: And no provision for any kind of fastening contraption - useless!:angry:
