Quick-Flip Dropper Caps for Hobby Paints

Green Stuff World’s flip-top dropper caps are a universal upgrade for most dropper bottles on the market with standard 10 mm diameter necks. The magic is the built-in lid: a flip-top hinge you pop open and shut with one thumb—no threads, no loose parts. While your other hand keeps a brush or airbrush steady, you can squeeze the bottle, grab a drop of your favorite acrylic paint, ink, or enamel, and snap it closed before the paint has time to skin over.

Each cap ships with the nozzle factory-sealed; one quick poke and you’re ready to roll, so no paint evaporates or leaks on the shelf. Just below the tip, a tiny catch cup traps the last micro-drop, keeping the spout spotless—no more crusty clogs that smear paint all over your fingers.

Open–close action takes a heartbeat, which means faster color swaps and more brush time. Because the lid is part of the cap, you’ll never mix colors by accident the way you can with loose screw tops. The flow rate is tuned for a precise, skinny drop—perfect for normal thinning or direct-to-airbrush mixes without wasting a single pigment.

Airbrushers get double value: keep the airbrush in one hand, flip the cap with the other, and dribble exact doses of your color, thinner, or retarder straight into the cup—no setting the airbrush down, no panic spills. For scratch-builders and display painters, the rapid seal limits air exposure and stretches the working life of metallics, washes, and specialty effects.

We have developed a cap made entirely from recycled plastic, taking another step forward in our commitment to the environment: the raw materials are reincorporated into the production cycle, maintaining the same quality and reliability that you demand at your painting table.

Sold in packs of 10, they let you retrofit an entire color range at once or keep spares ready for fresh bottles. Cleaner, quicker, zero waste— our Flip-Top dropper caps turn any standard dropper into a pro-studio tool.
