These are a few of my "Necktie Sacs/Pouches".
They are Sacks (Sac is French) for cellphones,
digital cameras, Iphones, eyeglasses, wallets. etc.
Some have a "button on" strap to give you "hands-free" maneuverability.
When you don't want to utilize the strap,
merely unbutton the strap and put it in the inside top pocket for storage.
The Sacs with straps are $15 each (includes postage)
and without the strap, $10 each (includes shipping).
