I have two bottles of Bulletproof Black and a bottle of Britannia's Blue Waves. One bottle of black has filled a single small converter (Pilot Vanishing Point), and the other is unopened. The BBW has had two converters worth (but since the bottle was filled to the very rim when I bought it, you'd hardly notice).

I'd like to trade the above away for other Noodler's Eternal inks. I'd like Heart of Darkness and Galileo Brown, but I'm open to suggestions. I'd also consider Aurora Blue.
