Ensso Black Aluminium Bolt Action Retractable Fountain Pen

RETRACTABLE NIB FOUNTAIN PEN

In the world of fountain pens, there are very few offerings for a retractable nib. BOLT is ēnsso's new bolt-action retractable nib fountain pen crafted in black space-grade aluminum. 

AIR-TIGHT MECHANISM

They developed an innovative air-tight mechanism that seals the nib from exposure to air when the pen is closed/retracted. There is a silicone seal with an 'X' cut that allows the nib to go through and naturally seals off when the nib is retracted. The mechanism has been tested for over one year and it allows the nib to remain wet for months.

BOLT-ACTION OPERATION

For quick, one-hand operation, the pen relies on a bolt-action mechanism in which a crown at the end of the pen is pushed forward to extend the nib. As soon as the crown is moved away from the lock position, the spring automatically retracts the nib. This simple solution is ideal and has minimal components.

INTERCHANGEABLE NIBS / INK CONVERTER

BOLT comes equipped with an ink converter for bottled ink. Its nib system is interchangeable and nibs in fine point and medium point will be offered.
