I still have it and it has held regular bulky portable phones (2 or 3 brand/models) and a smart phone. The interior is very soft almost Ultrasuede like.
I got it because I used to wear my portable phones in an open top, north/south oriented, novelty pouch around my neck.
After a downpour got my phone wet and I heard about the danger of cell phones too close to the body, I searched very intensely for an alternative.
The Cork Pouch discovery was an enormous blessing, it was clipped in the key ring of a novelty lanyard and carried in the outer pocket of my Cafe Bags.
Since I now, use a Clear Pink Small Organizer Pouch, the Pouch and phone are tucked inside the bag between Organizer Pouches which contain soft material such has cloth headbands or tissues or even my portable needlework project contained in a Stuff Sack.
Now that Tom has created, the Organizer Wallet, I believe that a Cork Pouch with Ultrasuede lining or flaps, made just like the dividers of the Organizer Wallet is possible.
But... I am not sure, because I don't sew and I don't design bags and other accessories.
