The Blue Drawer is one of the most widely distributed containers in the game. It's a small drawer with a blue finish that shows up across virtually every major sector. If you're running any map, you are likely to be encountering these. The loot pool is surprisingly broad. On the crafting and utility side you've got Chemicals, Duct Tape, Durable Cloth, Fabric, Torn Blanket, Household Cleaner, Laboratory Reagents, Antiseptic, and Syringe. These are solid across-the-board materials, recyclables, and valuables. For weapons, Simple, Medium, and Heavy Gun Parts all appear, making Blue Drawers one of the few common containers that can drop such high-tier crafting materials. Also worth noting: these containers seem to drop Mods, Blueprints, Keys, Quick Use items, and other items of that nature. The rest of the pool are mainly valuables: Red Coral Jewelry, Silver Teaspoon Set, Fine Wristwatch, Music Album, Poster of Natural Wonder, Dart Board, and Rubber Duck. None are crafting essentials but they sell decently and add up over a full run. Blue Drawers are worth looting on almost every run. The pool is wide enough that you'll almost always pull something useful, and they're so common across Dam, Research Control, Buried City, Hospital, Space Travel, Red Tower, Blue Gate, Ancient Fort, Spaceport, and Launch Towers that skipping them consistently means leaving real value behind. Fold them into your path. They have the potential to be worth a lot, but even on their own, they're reliable background income. Also, they are quick to loot as they do not require a breach or long animation.
