One of our most popular inks, Tesla Coil will produce a sheening effect when saturated on high-quality papers like Tomoe River and Rhodia. Our writing sample in this listing was made on 68 gsm Tomoe River paper. This hue will pull toward a strong medium blue with more sorbent papers. Tesla Coil is part of the Keystone Formula fountain pen ink line, our traditional dye-colorant ink. The 100mL volume will provide approximately 125 standard converter refills assuming a 0.8mL draw. Our ink swatch is produced with a cotton swab on Tomoe River paper. Enjoy Tesla Coil as a standalone fountain pen ink, or blend it with other Birmingham Pen Co. fountain pen inks to craft your personalized shade.
