Thank you! 😊

No it's not a sumi brush, but they do look similar!

(please excuse me for using this opportunity to ramble about brushes)

I used the ones on the left, I just know them under the name "french watercolor brush". The most obvious difference is the binding, the wires can be a bit uncomfortable if you tend to hold your brushes too close to the tip. They're made from Siberian squirrel, the hair is a bit coarser which makes it super absorbent, great for big areas. Also they are rather round, a sumi brush always has a super fine tip for nice calligraphy brush strokes. I don't own any though, so I can't really make a comparison. I really like these brushes, it takes forever until you need to load up the brush with color again and they just feel very luxurious to use. But they're not ideal for detailed work, they're delicate, so absolutely do not use them with inks, and they tend to be very expensive.

The next ones are some synthetic brushes I got in a multi pack for super cheap, they're meant for school level art, but they have a lovely tip and are great for all types of use. They're sturdy and I use them for inks without worrying about ruining them.

Next up are synthetic flat head brushes, I really love these for controlled working as they take up very little liquid. I also use them for trying to lift color off when I make a mistake, as you can apply pressure on the paper with them, which is not really possible with fine tipped brushes.

And the last group are standard watercolor brushes made from red sable hair. Again the natural hair makes them delicate and expensive. They're very good quality and I especially like to use the extremely thin ones for super fine details. But I believe that there are several synthetic alternatives that will give you the same quality.
