Review on 🖋️ Kuretake Fude Brush Pen - Retail Package, Fudegokochi (LS1-10S): Explore High-Quality Japanese Calligraphy Tools by Amber Perez

Pen was impressive on first test considering there is video of someone holding a dry pen. Mine was ready for anything I threw. I did a test on my paper and found it to be much more pressure sensitive than I imagined, but I bought this pen to try something new so I was happy! However, if you run an eraser over it, the ink will fade. I've found a few odd features of the pen that I have no idea what they are for: The cap has a small section at the top where you release pressure (by closing the pen or squeezing it when it's closed on the other side is). will open. Maybe it's for safety? I have no idea. At the other end of the pen, a black piece can be removed to access the ink reservoir, but it appears to be sealed, with a small round ball attached to the flat surface. Finally, can this pen be reusable? I'm not sure, but I won't try until I've almost destroyed the quill. In any case, TLDR is pressure sensitive.
