I got 4 of these a couple of years ago Vic, Axminster had them on sale at £10 .. Like Niel says, the elastic does stretch and two of the four inners came out .. If i was to buy now it would be the cases that Woody linked to .. I can also say that the cases haven't had much hammer also .. But not a bad case over all .. 
Would rather have the case that Steve just posted up thou ..
