Hi,
Why not just use a plastic resealable freezer bag? Or an old fashioned tobacco pouch?
BTW, the soft leather pouch for the CL was part no: 14,542.
BTW 2, if I was going to make one I'd buy one of those large lens cleaning clothes and make it out of that. A simple pouch with (say) a fold over Velcro fastening shouldn't be that hard to make.
