Working in industrial design, I constantly acquire small sets of parts to use for multiple clients and projects. I’ve tried using a variety of translucent plastic boxes to contain and organize these parts, but they’ve been flawed in a number of ways: the parts are difficult to pick out with your fingers; the small pieces migrate from compartment to compartment; and finally, the latches break.
I think Akro-Mils has solved all of these problems with their cases. The latches span the entire front side of the organizer, work well, and don’t seem to break. The bottom of each compartment is curved on at least two sides to allow picking up those 0-80 screws, and the top has ridges that surround each divider to make it much less likely for the parts to jump out of their compartments. The two Akro-Mils organizers I have been using are the small (05-705) and the large (05-905). There’s a medium available, too. I think I paid $4 and $7, respectively, which is about the same price as products with none of these features or durability.
