The angle of holding the pen is about 40-50 degrees, and the rotation angle does not exceed 30 degrees. Because the horizontal writing surface of the stub nib is relatively small, if you hold the pen too high or too low, and rotate the pen at an excessive angle, the entire writing surface will become distorted. Small, and may even scratch the paper. Thank you. If the angle you hold the pen does not meet this range, this nib is not suitable for you. Please take a photo of the writing angle. You need to customize the nib specifically for you. Thank you.
