This has to be a great box for an angler who is fishing bonefish on flats which have normal to small prey and average size fish. In this box there are eight compartments which have snap lids. These compartments are best sized for #8 & #10 flies. The other side has one large compartment which can be divided into up to 8 compartments which are covered with one large snap lid. These compartments can be configured to hold size #2, #4 & #6 flies. This box is transparent blue.
