I found a whole lot of cases for what must be small electronic gadgets - minidisc players and the like - at a local shop which takes bankrupt and excess stock and sells it cheaply. .

I bought a couple - one which will hold a glasses case and one twice that size. Both together cost three UK pounds - they were only nylon but the more expensive ones were both mock and real suede and leather, and there were many different shapes and sizes.

They had belts or straps as well as belt loops and hangers of various kinds so very versatile and rather handy for odd and ends

If you have similar shops it might be worth looking around in them.
