Speedball has been a trusted name in handcrafted nibs and pens for the calligrapher, letterer, and drawing artist for over 100 years. These Flexible Pen Point Nibs are also known as Hunt Artists' Pen Nibs. The No. 512 Bowl Pointed nib features an extra fine, semi-flexible tip for ruling and lettering. Its rounded, bowl-point tip allows the nib to glide smoothly over the paper without scratching. It fits in standard pen holders.
