(5 Pack) R. Esterbrook & Co. Vintage Calligraphy Pen Nibs - #702 School Med Firm
 
The R. Esterbrook & Co. #702 School Medium Firm nib is a hallmark of mid-century American education, specifically designed for students to master disciplined, uniform handwriting. Produced predominantly in the 1940s, this nib is distinguished by its dramatically tapered body and a uniquely shaped vent hole that balances ink flow for long classroom sessions. While these specific units are stamped "School Medium Firm," they are technically identical in design to the earlier and highly sought-after "#702 Modified Slant," which was a staple for rapid, slanted ledger writing and business correspondence.
Constructed for durability and consistent performance, the #702 offers a "medium-firm" action that provides excellent control for beginners while still maintaining enough flex to produce a range of lines from hair-fine to approximately 0.9 mm. Its sharp point is finished with curved side cuts and groove stamping, features that modern calligraphers prize for adding subtle "personality" and shading to both script and pen-and-ink drawings.
