These awesome fine tip Japanese brush pens should be in the inventory of every lettering artist. They come in black inkandwith two different tips: hard and soft.
The hard tip is a perfect beginner's brush pen. as it's easy to control and very distinct. Drawing those fine hair lines are suddenly very doable. but it can still make quite a broad line too. which make up for a nice contrast within your letters.
The ink flow of the soft tip are a little bit juicier and thus. alittle bit more black.
