To the best of our knowledge the price point we offer is among the most competitive industrywide for a wholly acrylic fountain pen that's been fully machined in the U.S.A. from raw stock. Acrylic is a particularly difficult material to work with since it's hard like glass, has a low tensile strength, and can be prone to melting if the machining feed, speed, and tooling aren't calibrated correctly. Dad and Nick have spent countless hours designing custom tools and adjusting the fabrication process to produce a rigid, functional, and beautiful output.
Every heirloom quality Sankara Stone fountain pen includes our 100% satisfaction guarantee and lifetime warranty.
Please allow 1-2 weeks to ship pens manufactured in-house. We prepare and ship pens as fast as possible but our output speed varies with order volume.
