Double-sided brush/pen is great for calligraphy crafting where it’s possible to combine the characteristics of the two different endings as needed. There’s a brush on one end thanks to which it’s possible to easily create thin as well as thick lines, and there’s a firm tip on the other end that’s more suitable for writing and details. The brush is durable and flexible at the same time, therefore its strokes will always be just as you want them. Its combinability makes this pen suitable for those who are just starting with calligraphy.
