You could build this with some knowledge in either:

Duct-tape manufacturing

Cardboard cutting and Hot-glue

Or you could build a soft sack to do the same trick with an old shoelace and some sewing knowledge (sew a piece of cloth to itself (so a 10" x 4" piece for your specifications) and then wrap down the top edge over the shoelace and sew it over to make a drawstrap for it [leaving somewhere to actually access the drawstring, of course], you just need a shoelace [or really any piece of string] 5" long or more. Then sew a 5"x5" square to the bottom to make the pouch able to hold stuff). A hint with this: tie the shoelace's ends when your done to prevent the lace from getting withdrawn into the slide.
