Faber-Castell, founded in Germany in 1761, is one of the oldest names in writing, and this Rainforest pen carries that heritage.

The Neo Slim design

The Neo Slim is exactly what its name promises: a slim, elegant fountain pen with a narrow 9mm body that slips into a shirt pocket, a planner loop or the smallest pen case. Despite its slender profile, it has a solid metal body and a reassuring weight, so it feels like a quality instrument rather than a lightweight everyday pen. Its clean, minimalist lines make it a natural choice for people who prefer understated design.

The Rainforest finish

Rainforest is a deep, dark green inspired by lush tropical forests. Faber-Castell pairs it with shiny gold-tone trim on the front section, end piece and spring-loaded clip, for a rich, elegant look.

It was released as a limited edition alongside the creamy white Marshmallow, so it is a collectable variation of the Neo Slim. The nib is gold-plated stainless steel to match the trim.

The nib

The Faber-Castell Neo Slim Rainforest fountain pen has a gold-plated stainless steel nib, smooth and dependable, with a gentle amount of give. We offer the Rainforest Neo Slim in Extra Fine, Fine, Medium and Broad.

Size and weight

The Faber-Castell Neo Slim Rainforest fountain pen is about 140mm long capped and 156mm with the cap posted, 9mm across and about 20g. The snap cap of the Rainforest Neo Slim clicks on securely and posts firmly on the end, which gives a comfortable full-size writing length.

Who it is for

The Faber-Castell Neo Slim Rainforest fountain pen is ideal for anyone who wants a fountain pen they can carry every day: students, doctors, lawyers, journalists and travellers. The slim Rainforest profile also suits writers with smaller hands, and the Faber-Castell Neo Slim Rainforest fountain pen is an excellent first fountain pen for someone moving up from ballpoints.

Choosing the right nib

Here is a simple way to choose your nib. Pick Extra Fine if you fill planners, write in small notebooks or use thin paper. Pick Fine for everyday notes, forms and office work. Pick Medium if you want a smooth, relaxed writing feel and stronger colour. Pick Broad for signatures, headings and journals where you want your ink to shine. All of these are steel nibs, so they are sturdy, forgiving and ideal for daily use, whether this is your first fountain pen or your fiftieth.

Cartridges, converters and bottled ink

Filling is easy. The pen takes standard international ink cartridges, which you simply push into the grip section until the pin pierces the cartridge. If you prefer bottled ink, fit a Faber-Castell standard converter and draw ink straight from the bottle: dip the nib, turn the converter's knob and watch it fill. Bottled ink is more economical in the long run and opens up thousands of colours.

Ink recommendations

The Faber-Castell Neo Slim Rainforest fountain pen works with any good fountain pen ink. Here are a few colours we especially like with the Rainforest finish, all available at Makoba:

• Graf von Faber-Castell Deep Sea Green: a deep green that echoes the barrel
• Graf von Faber-Castell Moss Green: a natural, earthy green
• Graf von Faber-Castell Olive Green: a soft, vintage olive
• Graf von Faber-Castell Midnight Blue: a classic blue-black for formal writing

You can also browse our full range of fountain pen ink bottles and ink cartridges to find your perfect colour.

Caring for your fountain pen

To keep your pen at its best, cap it between writing sessions and rinse it with lukewarm water whenever you change colour. Do not leave ink sitting in an unused pen for months; empty and clean it first. Wipe the barrel with a soft, dry cloth to keep the finish bright, and carry the pen in a case so it does not rub against keys or coins. These small habits make a big difference to how long a fountain pen lasts.

The Neo Slim family

Alongside this Rainforest pen, the Neo Slim family includes fountain pens, ballpoints and rollerballs in finishes from polished and matte stainless steel to black lacquer, brushed aluminium and limited-edition colours. All of them share the same slender profile and snap cap, so the Rainforest fountain pen fits neatly into a matching set. A Neo Slim ballpoint and fountain pen in the same finish make a practical pair: the ballpoint for quick forms and signatures, and the Faber-Castell Neo Slim Rainforest fountain pen for notes, letters and journalling.

A gift worth giving

This pen makes a thoughtful gift for students, professionals and anyone who still enjoys writing by hand. Unlike most gifts, a good pen is used every day and often kept for decades. It is a popular choice for birthdays, Diwali, anniversaries, new jobs and corporate occasions, and it comes in the original brand packaging.

Pair it with good paper

Paper matters as much as the pen. A smooth, well-sized paper lets your pen glide, keeps your writing crisp and shows off the colour of your ink. Explore our range of notebooks, journals and pads to complete your writing set.
