✨ Design and appearance highlights

The overall design pays homage to the classic writer's pen style. The pen cap is made of glossy black resin + gold-plated streamlined pen clip. The pen barrel is available in ** warm orange, pearlescent white, sapphire (black and gray resin pattern)** and other colors. The wave-patterned gold-plated middle ring in the details enhances the texture. The pen grip area is made of black resin, taking into account anti-slip and writing comfort.

It has a built-in all-brass piston structure. Compared with the ink bag/absorber of ordinary fountain pens, it has a larger ink filling capacity and longer battery life. The brass material is highly durable and is less prone to stuck and ink leakage problems after long-term use.

No. 6 35 tip: suitable for daily writing questions and accounting, EF/F tip is fine and smooth;

No. 8 No. 40 large nib: The size of the feed + nib is larger, and the water is more abundant. It is suitable for practicing calligraphy, signing, and English writing. It has a slight damping feeling and clear feedback.

📌 Configuration details analysis

Hard rubber tongue: a material only used in high-end pens. Compared with ordinary plastic pen tongues, it has better ink affinity, can stably control water, reduce whitening and ink breakage, and is not easily corroded and aged by ink after long-term use.

Brass piston + resin pen barrel: The brass piston ensures structural durability, and the resin pen barrel avoids the overweight problem of an all-metal pen barrel, so your hand will not be tired when writing for a long time.

Bright tip design: The pen tip is exposed, which makes it easy to observe the writing status, and also facilitates subsequent polishing and replacement of the pen tip. It is highly friendly to pen players.
