The Bronze Age, which Visconti's Italian shop calls Lava Bronze, pairs the black lava with bronze trim and a rose-gold 14k nib. On October 22, 2026 it was number 1 on Goulet Pens' best-seller list. It's also one of the picks in our [most collectible pens](https://stationerytimes.com/guides/collectible-pens/) roundup. ## Visconti Homo Sapiens Bronze Age specs | Spec | Homo Sapiens Lava Bronze (KP15) | |---|---| | Length capped | 146 mm (5.7 in) | | Length posted | 173.4 mm (6.8 in) | | Body length (with nib) | 132 mm (5.2 in) | | Diameter | 14.3 mm body, 16.5 mm cap, 21 mm with clip | | Grip | 11.0 mm, lava | | Weight | 44 g (27 g body, 17 g cap) | | Nib | 14k gold, rose-gold plated; EF, F, M, B and S (stub) | | Filling | Titanium vacuum power filler, about 1.51 ml | | Cap | Bayonet, a quarter turn | | Trim | Solid bronze | Measurements and capacity are Goulet's; nib sizes, filler, cap and size class (Visconti calls it Over) come from Visconti Italy.

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](https://stationerytimes.com/guides/how-to-fill-a-fountain-pen/) 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. | | Homo Sapiens Bronze Age | [Pilot Custom 823](https://stationerytimes.com/guides/pilot-custom-823/) | [Montblanc Meisterstück 149](https://stationerytimes.com/guides/montblanc-meisterstuck-149/) | |---|---|---|---| | Filling | Vacuum power filler | Vacuum plunger | Piston | | Capacity | 1.51 ml (Goulet) | 2.55 ml (Goulet) | about 2.1 ml (Galen estimate) | | Length capped | 146 mm | 148.4 mm | 146.1 mm | | Weight | 44 g | 29.5 g | 30 g | | Nib | 14k (18k option) | 14k No. 15 | 14k or 18k | | Body | Lava and resin | Resin | Resin | For a lighter, cheaper way into the brand, the [Visconti Mirage Mythos](https://stationerytimes.com/guides/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. ## Frequently asked questions ### Is the Visconti Homo Sapiens really made of lava? Yes, mixed with resin. Visconti says its artisans combine basaltic lava from Mount Etna with resin by a secret process, which Goulet describes the same way. ### What is the difference between Homo Sapiens Bronze Age and Dark Age? The trim and nib. Bronze Age has polished bronze trim and a rose-gold nib; Visconti's Dark Age has black galvanic trim, a ruthenium-finished gold nib and an anti-stain finish on the lava. ### Does the Homo Sapiens take cartridges? No. Goulet lists bottled ink only: the pen fills through its built-in vacuum power filler, which holds about 1.51 ml. ### Is the Bronze Age trim plated or solid bronze? Solid bronze, according to Goulet, and Visconti lists the trim simply as bronze. We haven't yet tracked how it ages; our long-term test will photograph it over a month of use. ### Is there an 18k Homo Sapiens Bronze Age? Yes. Goulet sells 14k and 18k versions; on October 22, 2026 the 14k was first and the 18k 44th on its best-seller list. ### Can you post the Homo Sapiens cap? Yes. Goulet lists it as postable, at 173.4 mm long posted, though that makes a long pen. ### Is the Visconti Homo Sapiens made in Italy? Yes. Visconti is based in Florence and says its pens are handmade there; Goulet also says Visconti makes its pens in Florence. ## Sources - [Visconti (Italy): Homo Sapiens Lava Bronze penna stilografica (KP15, €900 incl.
