WAY more rugged than the requirements of an office job, bag4 is effective nonetheless. I've been carrying this inside my bag2 shoulder bag to keep the little things organised in a small #dumpbag. I've been using it to keep a micro USB cable, battery booster, headphones, headtorch, sun glasses, lighter, utility knife and tool set, bulldog clip, ear plugs, keys.. all drop easily in this hand sized pouch that sets down stably wherever you put it. Excellent nail bag! Roll top closure has been tucked in and out of the way for daily use.
More on the 4+ part modular bag system soon.
