This 'Immortal' EDC Pen Spent 24 Hours Underwater, And Still Wrote Continuously For 1,500 Meters - Yanko Design
"Thomas Slim immersed their new EDC fountain pen in water for 24 hours, pulled it out, and it wrote immediately. They dropped both the fountain pen and rollerball versions fifteen times from one metre onto concrete, and aside from minor ink on the nib face, both kept writing without issue."
"The grip section secures the cartridge firmly under impact, solving the problem most cartridge pens face when they hit pavement. The fountain pen uses a Schmidt nib, polished in-house for smoothness, which matters if you're writing more than a quick note."
The Thomas Slim EDC Pocket Pen is designed for durability, featuring a water-resistant build and impact protection. It is made from 304 stainless steel and weighs 36 grams. Both fountain and rollerball versions utilize the same cartridge system, ensuring flexibility and ease of maintenance. The internal grip prevents cartridge movement during impacts, while capillary channels manage ink overflow. The fountain pen includes a polished Schmidt nib for smooth writing. Available in three finishes, it combines precision engineering with practical functionality for everyday carry.
