I guess you have a different case from mine. Mine is actually a bit too loose. DX50 slides in and out easily. The exterior is something like black velvet and the interior sort of gray silk.
The loop to close is a plastic transparent ball attached to a black string on one side and a black knot on the other side.
I dunno what you guy are talking about cause my case is awesome I mean I can't really ask for a better case for a DAP of that size. The velvet feel to it is perfect plus you can control the music without taking it out and also teh open gap nature of the case allows cables to pass through.
Moreover it looks really nice when I place my DX 50 on top of the pouch on a surface and it makes it look so good and classy.
