How does the tip extend and retract — is there a twist mechanism?
Yes. Rotating the barrel extends and retracts the writing tip. There is no separate piece to remove or set aside before writing. To extend the tip, twist the barrel in one direction; reverse the twist to retract it fully. This keeps the writing point protected when the pen is in a pocket or a bag. The mechanism is built into the barrel of a pen turned from Italian resin, so the same part you grip to write is the part you turn to ready the tip.
What refill does this ballpoint take, and where do I get a replacement?
When you need a replacement, the Thalassa ballpoint accepts a Parker-style G2 ballpoint refill. Yafa stocks the Schmidt P900, a large-capacity Parker-style G2 ballpoint refill, under item number SC58135. That is a compatible replacement available directly through Yafa. Name the standard when ordering from other sources: Parker-style G2 ballpoint refill. Beyond that, what fits is what the standard covers, and what Yafa stocks is the Schmidt P900 at SC58135.
What is the Thalassa finish, and what does it look like on the resin?
Thalassa is the colourway name for this pen. The barrel and body are turned from a solid rod of Italian resin. Layered blue tones give Thalassa the movement and depth of open water. The finish makes the pen expressive without losing the polished restraint expected from an Italian writing instrument. Palladium trim completes the pen. If you are choosing between colourways, this one reads as a deep, shifting blue rather than a flat or uniform colour.
Where is this pen made, and what is the background of the Nettuno brand?
Nettuno traces its origins to Bologna in 1911, when founder Umberto Vecchietti used the city's Neptune fountain as the symbol for the brand. Today's Nettuno pens are manufactured in Naples by Maiora Pen Company. The N-E in the model name stands for Nineteen Eleven, a reference to that documented origin date, and 2.0 marks this as the second iteration of the line, released in 2024. The pen is made in Italy from Italian resin turned from solid bar. Yafa Brands is the official US distributor.
