Calligraphy without the dip pen
A dip pen means stopping every few words to re-ink. The StoneGraph holds its ink like a fountain pen and flexes like a dip nib: press a little and your strokes swell from a hairline to a bold line. Made for lettering, cards, invitations and journals.
“This is so much easier than using a nib! I have addressed party invitations and Christmas cards! It is terrific... I am planning on getting another!”
— Anne E., verified buyer
