Fountain Pen
The lightweight smooth writing pen is simply designed with a grayish white color. A black ink cartridge is included. (Insert the stainless steel ball of the cartridge from below with the nib facing up.) The compatible cartridges are polycarbonate pen cartridges containing 4 black inks (4550344596906) and 4 blue-black inks (4550344596913). *Wait for the ink to seep into the nib and repeat the test writing several times until the ink flows smoothly. If writing is not smooth, it may be due to ink clogging. Please clean the nib with warm water and dry the water with a piece of soft cloth before use.
