Since I bought toppers in groups I transferred all the spares and extra parts to Tupperware-type containers. Spare mods are still in their original boxes, though. I have pill-size Ziplock bags for each size & type screws, each size & thickness o-ring, extra drip tips by size, color and diameter, etc. In prepping for vaporgeddon, I got a bit organized and have about 14 (I checked) spreadsheets. The combination to the bunker's vault door...I, well, I guess I shouldn't say.
Oh, you can tell us the combination. We won't tell anyone else.
