Amazing pens! It comes in five 0.05mm, 0.2mm, 0.4mm, 0.6mm and 0.8mm in nib sizes. It is perfect for my drawing and writing. I am starting to learn how to calligraphy and these are kind of cool to try them out. I mostly do a lot of sketching and these pens work perfectly. The ink flow beautifully and smooth. I am so glad to find them online. The price was not bad either especially for five pens. https://www.amazon.com/gp/product/B078J7JZYK/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
