A number of people have asked me what ink I put in the Lamy Safari fountain pen I use in the Spring video. It’s a lovely substance called “Noodler’s Black Waterproof Fountain Pen Ink” which is incidentally classified as “Bulletproof” because, once dry, it “resists all the known tools of a forger, UV light, UV light wands, bleaches, alcohols, solvents, petrochemicals, oven cleaners, carpet cleaners, carpet stain lifters …” In short, don’t spill it on your nice new shirt.

I bought my initial bottle on Amazon for about $12 but I see it’s now up to $16.18. As that first bottle has lasted me for nearly two years and is still going strong, I consider it a bulletproof investment.
