A handy box for those who like to tie lots of flies and keep them in order. The box perfect A4 fit and will be do good on shelves, stacked or not. 

OK quality but because of size, the plastic can be a bit wobbly. Stack flies from top down and do not push too much on the foam inserts. 

The A4 is practical and easy for stacking in a system. Logo can be pealed off for full clear view.
