I have added two of this smart phone hard cases into my Etsy shop just now.
One thing I was not sure of, and was confirmed by the customer at the event,
was this short leather strap.
I have changed it to the long strap.
This leather strap has 2 length capacity.
When you pull one strip like this
the strap becomes long
so you can wear it like this
if you pull 2 strips like this
and you make it short
so you can use it as a shoulder bag.
There are 2 of them in my Etsy shop now, and one ipad 2,3,4 case.
My Etsy shop will close again from mid June till mid July.
