Measurements and capacity are Goulet’s; nib sizes, filler, cap and size class (Visconti calls it Over) come from Visconti Italy. Goulet’s spec sheet lists only EF to B.
The capped pen is 146 mm; posting the cap makes it 173.4 mm, per Goulet.
Why does Visconti use lava?
For its feel and toughness: Visconti says lava stone resists scratches, water, limescale and sudden temperature changes, and is hygroscopic. That last property means it absorbs a little moisture, which Goulet says makes the pen comfortable and warm to the touch.
Visconti adds that the stone’s look depends on how it is cut: surface layers are more porous, deeper ones more compact, and the final finish is done by hand. Expect each pen’s grain and speckle to differ slightly.
How do the cap and filler work?
The cap locks with a short twist, and the pen fills straight from the bottle with a vacuum plunger. Visconti calls the cap a bayonet system: twist gently to close, push toward the barrel and turn to open. Goulet calls it the Hook Safe Lock and measures a quarter turn.
The power filler is a vacuum (plunger) filler made of titanium to resist ink corrosion, per Goulet. It holds about 1.51 ml and takes bottled ink only; our fountain pen filling guide explains how vacuum fillers work.
Which Homo Sapiens should you choose?
Choose by trim, nib metal and finish; Visconti’s lava pens share the same shape. Visconti’s Italian site describes three lava versions.
Lava Bronze (Bronze Age): black lava, polished bronze trim, rose-gold nib. Goulet sells 14k and 18k nibs.
Lava Dark Age: monochrome dark grey, black galvanic trim, a ruthenium-finished gold nib and an anti-stain finish on the lava.
Lava Color: lava in colored finishes.
Visconti also sells non-lava Homo Sapiens pens, such as the new Carbon Rose in carbon fiber with rose-gold anodized Ergal trim.
How does it compare with other luxury vacuum and piston pens?
It is heavier than its rivals, with a smaller ink capacity than Pilot’s vacuum filler. Figures for the other pens come from our guides.
For a lighter, cheaper way into the brand, the Visconti Mirage Mythos has a steel nib and takes cartridges.
Where is the Visconti Homo Sapiens made?
In Italy. Visconti is based in Florence and says its pens are handmade there; Goulet also describes Visconti as making its pens in Florence. Visconti doesn’t publish a release year for the Homo Sapiens on its current site, and we couldn’t confirm one from a primary source.
