It is an excellent compact, watertight and reliable box in which you can carry all your dry flies, nymphs and streamers for a day or a weekend. Suggestions for improvement: (1) the bottom of the compartments could be made in a light color to improve the view of the flies. I have lined them with cream foam. (2) Several compartments could be subdivided with a simple clear plastic that the customer can install or not, according to his needs. I subdivided them with small wooden slats, and managed to almost double the number of compartments. (3) A couple of compartments could be merged into one, allowing to carry streamers.
