I am looking for the black rubber strap with clasp as seen in the attached pictures for the Ploprof. If you have just the clasp or strap I would potentially be interested as well, in new or used condition. Thanks

 

Still looking, hoping someone has one sitting collecting dust they would let go.

 

The Boutique said they can get me the set (black strap, clasp and spring bars) for $557. If nobody has one I guess that is the route I will go.

 

To close the loop, acquired what I needed.
