I purchased a couple of Plano thin tackle boxes. The larger box can be divided in to 10 different compartments.
The smaller one I am currently using. The box contains some of my small drill bits. It is holding my FDUR 1,3,5,7, and 9. I have made labels for the outside of the box. When I need to switch to a different blade I tape it to the lid corresponding to that blade size storage bin.
