The flies boxes are comfortable and practical, as the name says, they are used to contain neatly or not, this is up to you, the flies. Normally made of plastic, inside they have shaped or cut foam sheets or strips. Thanks to the cuts on the foam we can store the flies by fitting the tip of the hook in the cuts.
There are also boxes for flies in the soft part in foam do not have cuts, these are normally more convenient for storing the streamers because they are more bulky both for the size of the bait and the hook.
The flies boxes are also used in spinning fishing, allowing you to also store minnows, spoons and spinfly baits in an orderly way.
