Overview

Not a pen for experts only, this fountain pen is built for novice and experienced users alike, with a medium nib and a smiley face marking the correct writing position. The hexagonal barrel makes it easy to hold.

A shaped barrel and a marked nib help newcomers find a comfortable grip quickly. Colored caps let a buyer choose a look. The title calls the barrel clear while the description says gray, so the finish should be checked.

Who it's for

Students, note takers and bullet journal writers learning fountain pens can lean on the grip guide. The medium width suits everyday notes. Writers wanting a fine nib or a clear list of included parts should check the maker's details.

  • Hexagonal barrel resists rolling

Performance notes

The smiley face on the nib marks the writing position, which guides the hand without instruction. Medium width lays down a line that is visible on most notebook paper. Flat faces on the barrel give fingers positive contact.
