.5 Ounce (15ml) plastic dropper bottels just like the ones that Vallejo paints come in. Perfect for mixing your own colors and saving them, dispensing adhesives, applying washes, and many other other uses. Also great for buying thinners, airbrush cleaners and flow inporvers in bulk to save money and then transfering them into dropper bottles to make them easier to use and store on your workbench.
