First and foremost, it's an illustrator's or calligrapher's delight, allowing you to adjust the nib to create a variety of stunning line variations. Simply twist the thumb screw to produce a broader or finer line, or adjust the angle of the nib to the page to achieve the juiciest thick strokes. Playing with the One-Dip-Nib to create a variety of styles & novel techniques becomes completely addictive.\nWhy do you call it the One-Dip-Nib?Well, this is where things get interesting. I've become a bit of a capillary action geek over the years, and it turns out that with some clever engineering, it's possible to create an enormous ink capacity within the nib itself. Inside, you'll find a cavity with a reservoir that stores ink, allowing you to doodle an entire side of A5 paper without needing to dip!\nSounds interesting! Anything else you can tell me?\nThe Brass and Steel have unique benefits.The stainless steel nib is more precise and can achieve a finer line, and because it's more durable will hold its tip point for a very long time. Brass is a softer material and so feels smoother on the page and has a larger variation between thin line widths and thick when adjusting using the thumb screw.\nUse any ink!This is exciting, to say the least. Waterproof pigment, shimmer, iridescent, watercolours, acrylic, Indian... The list goes on. The One-Dip-Nib can be cleaned in a jiffy with no risk of clogging.\nA better choice for the planetI believe in building longevity & versatility into all of my designs. So, instead of buying multiple disposable fineliners with different tip sizes, you can use Indian ink & adjust the line width instead!\nUse it like a brush!Never before has a nib been able to double as an artist's brush, until now! By varying the angle to the page, the nib can create thick, juicy strokes or","images":["https://cdn.shopify.com/s/files/1/0089/6129/4417/files/one_dip_nib_in_packaging_brass_69fde6f2-d75e-49e3-b89c-87b31010a59e.jpg?v=1745324638","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/lifestyle_one-dip-nib_bc75ea6f-d510-4644-bc9e-7b8f71a5c31f.jpg?v=1745324638","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/stainless_and_brass_nibs_bc91bc15-1654-4f6a-8abd-538a385234e8.jpg?v=1745324638","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/angle-width-w-text_65a8bba7-3073-47b7-b8be-82d75b20fdc9.gif?v=1745324638","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/how_it_works_one_dip_nib_d7a08d81-0ac2-49da-8c32-0c9c40423761.jpg?v=1745324638","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/one_dip_nib_cleaning_cacca505-ae84-4818-a153-d53efe520c9e.jpg?v=1745324638"],"price":62,"currency":"USD","in_stock":true,"inventory_qty":39996,"dynamic_pricing":false,"listed_at":"2026-06-18T20:47:23.510Z"},"share_url":"https://firestarter.network/l/lst_j9Pjq3Ud","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
