Far more capable than the name suggests, the Inventery Modular Fountain Pen is an elegant, versatile writing tool worthy of even connoisseurs. It uses an all black Schmidt FH 241 fine point nib compatible with both the included 9 black ink cartridges and the K6 refillable cartridge converter. Thanks to it's modular design, it also has a 0.5 PRS ballpoint head and can be used with or without a clip, with a keychain attachment, or with the included stylus tip for electronic devices. Precision machined from brass with a black oxide finish, it arrives with a matching extender that takes the barrel length from a compact 100mm to a full-sized 128mm. The all black configuration is exclusive to Uncrate.
