The pin inside the section block will puncture the seal of the cartridges, allowing ink to flow into the section block. Screw the barrel on over the cartridge into the section block. When you fill the pen at the first time, you can swing the pen to make a few drops of ink coming out of the nib, so that it can flow easily. 100% Satisfaction Guarantee: If the cartridges you received are not in satisfied condition, please feel free to contact, we will fix the problem for you.
