Absolutely love this pen! The nib is slightly flexible which makes it easy to get line variation. Unlike a brush nib, this gives you more control of when you want to have a thick or thin line. The ink comes out nicely, not dry at all! I’d highly recommend this to anyone and will purchase again. Also, I’d like to note that this is a water based pigment pen but I use watercolor and have had very little issue with this ink smudging with water.
