I have a couple of these and I really like them a lot better than the Morell style foam fly boxes, even though the C&F fly boxes are a little heavier and smaller. One of my boxes has the leaf in the center of the box, which adds about 50 % more fly carrying capacity. Here is T-Bums' information on these light weight foam fly boxes: http://www.tenkarabum.com/c-and-f-li...-fly-case.html
