Each of these ink bottles easily solves that problem with a simple plastic tube in the bottle. Anyone who has ever filled a water bottle up and placed it upside down into a bowl will know how the phenomenon works, atmospheric pressure balances out so that the water in the bottle remains higher than the surrounding water in the bowl. In the case of this ink bottle, as the ink levels get low, simply tighten the bottle cap, flip the bottle upside down, and then flip it right side up. Ink levels remain higher within the plastic tube than in the rest of the bottle, allowing you to fill your plunger-style fountain pen with ease.
