i am positive this has been thought of before.
i was walking through walmart looking for some multivitamins, when i spied out of the corner of my eye a 7 day pill storage box that would make a great fly tying hook or bead storage box. add a few labels to cover up the days of the week and off you go! this box has small levers that you push down to open the compartment and the inside has a curved bottom. 28 compartments. the underside of the box has 4 rubber feet to prevent sliding.
thanks for looking
