Moonman fountain pens are part of the new wave of inexpensive fountain pens made in China that provide tremendous quality for an affordable price. Similar to PenBBS, these pens are designed by fountain pen enthusiasts looking for a high performing, everyday writing experience. The Moonman pen company describes the moonmen pen on the moonmen pens website as a fountain pen with an eyedropper-friendly design and reliable steel moonman nib (m2, m8). Please note the N1 design is not an eyedropper convertible fountain pen. Moonman ink cartridges are not compatible with international standard ink cartridges.
