🎨 Appearance and Design Highlights
1. Iconic Design Language
Hexagonal Nut Element: The pen cap and end both feature a hexagonal "nut" shape, complemented by a central plum blossom pattern. This is the core design element of the product name "PrismX," infusing an industrial feel into a minimalist design for maximum recognizability.
Contrasting Color Split Structure: The cap is made of colored frosted metal, while the barrel is made of silver-gray sandblasted aluminum alloy. The two-tone design creates rich visual depth while maintaining a balanced warm and cool feel when held.
Integrated Metal Clip: The clip is made of the same color metal, laser-engraved with the NATAMI brand logo. It has moderate elasticity and can be securely clipped to notebooks or pockets without easily deforming.
2. Color Options
Classic Options: Navy Blue, Obsidian Black, and Matcha Green (Olive Green). These three are shown in the image.
Extended Options: Also available in burgundy, purple, and other colors to satisfy different aesthetic preferences.
3. Craftsmanship Details
The pen body is made of 6061 aluminum alloy in a single piece, with a fine sandblasting/anodizing finish, making it wear-resistant, fingerprint-resistant, and scratch-resistant.
The pen cap has a built-in, top-mounted plastic liner, ensuring a tight fit even when worn upside down and preventing scratches on the pen barrel.
The threads are precision-machined with 6 turns, ensuring smooth screwing and easy alignment on the first try, with even resistance.

✍️ Writing Performance
1. Nib Experience
The nib is made of stainless steel with iridium alloy, featuring a finely polished surface, even slits, and a rounded iridium tip. It offers moderate resistance, eliminating the grainy friction often found in Japanese fountain pens, resulting in smooth and even ink flow, producing full, flowing lines in a single stroke.
The nib is on the firmer side with less elasticity, suitable for users who apply greater pressure. It provides stable writing without skipping, making it ideal for Chinese character writing, daily note-taking, calligraphy practice, and signatures.
The iridium tip is wear-resistant and has a long lifespan, making it suitable for frequent use by students.
2. Ink Filling System
It comes standard with a mini rotary converter with ample ink capacity. The filling process is simple, and the seal is excellent, preventing leaks.
Compatible with German standard ink cartridges, allowing for quick ink changes, suitable for commuting and business trips, eliminating the need to carry ink cartridges.
