CENTO3 — From design to products

Born in 2001 from the intuition of Achille Castiglioni and Gianfranco Cavaglià and completed in 2021 by EGOUNDESIGN, CENTO3 is a collection of writing instruments that combines formal research, ergonomics and contemporary production.

Its distinctive feature is the trilobate section, designed to ensure a natural, comfortable, and incredibly stable grip. This intelligent shape was born in 2001 and is now brought to life through digital manufacturing: each piece is created using 3D printing and finished by hand like in a modern workshop.

CENTO3 is designed for those who write, draw, and design. For those who consider tools an extension of their way of thinking.

The result is a family of pens that puts Italian gesture, material, and quality back at the center.

The four instruments

CENTO3.E — Multifunctional pen

The most versatile tool. The trilobed body houses a 5,6 mm refill that becomes a pencil, ballpoint pen, highlighter, or crayon depending on the lead chosen. It's perfect for sketches, quick markings, and handwritten notes, but also for anyone looking for a solid, technical, and designer-inspired desk accessory.

Includes black ink and HB graphite pen refill.
Compatible with TRILObyME all-in-one creative pencil case.

CENTO3.G — Pocket fountain pen

Compact, solid, essential. The pocket fountain pen takes the trilobate shape and translates it into a smaller format, convenient to carry anywhere. The steel nib offers smooth, controlled writing, ideal for those who appreciate fluidity and refined form.

For those looking for a contemporary fountain pen, free from nostalgia but full of character.
Refillable with standard cartridges. Black ink cartridge included.

CENTO3.O — Mechanical micromine

Designed with attention to detail in mind, it's designed for those who work with extreme precision: designers, illustrators, and architects. Its lightweight design and trilobate geometry ensure ergonomic use even during the longest sessions. Characterized by a fine, consistent, and light stroke, it's perfect for technical projects or everyday notes.

3 0.7mm leads included.

CENTO3.R — Roller

The rollerball pen offers smooth, continuous writing, ideal for everyday use: signatures, notes, and office work. Thanks to its steel tip, it offers unparalleled glide, ensuring a continuous, linear line. The trilobate shape designed by Achille Castiglioni in 2001 gives the pen a unique ergonomic grip that makes everyday use even more pleasant.

Refillable with standard cartridges. Black ink cartridge included.
