These Ketofa airbrush bottles are perfect for hobbyists and artists who use siphon-feed airbrushes. You get 10 plastic bottles, each holding 30ml (about 1.07 oz) of paint, which is a nice size for detailed model painting, customizing, or craft projects. The bottles come with matching lids that have a 30-degree down-angle adapter and a silicone cap to prevent leaks and evaporation. They also include 10 extra rubber caps for the suction tubes. The bottles are made of clear plastic so you can easily see your paint color, and each has a Teflon tube inside that resists corrosion from common solvents. Important: These are for dual-action, siphon-feed airbrushes only – not for single-action models. They fit most popular brands and make it super easy to switch colors or store mixed paints. A practical, affordable accessory to keep your workspace organized and your airbrush running smoothly.
