LOL......OCD huh? I call it attention to detail.

The parts box I use is actually part of a case with two such boxes. One case houses my spares, the other my cleaning gear. The top contains my armorers tools.

The clear containers once held avionics connector pins, I’ve collected them over the years from various employers. Similar containers can be had if you search using Google.

ETA: The labels are nothing more than Avery Labels which can be purchased just about anywhere. Microsoft Word allows you to print on the various labels available.
