Sakura Pigma Brush Pen Set of 9

I bought it to try. Good quality product. It arrived to me with no issues.

I liked the pens very much, they are enjoyable to write and the nib is thin The welded writing has a very elegant appearance, but the pens are in my hand. Although it has only been three or four days since it arrived, it would not be very noticeable. The ends have become slightly thicker. It doesn't affect writing much for now, but I didn't think about whether there would be excessive thickening over time. Though When I first bought the pens, I didn't know how to calibrate during the learning stage. I don't know if I forced the tip too hard or not. I'll update if I don't forget
