In-Depth Review: Chren Fountain Pen – Dual-Use (Cartridge & Converter) with Ink Refills



1. Product Overview

The Chren Fountain Pen (传人) is a dual-use fountain pen that offers both ink cartridge refill and ink converter (抽墨式) capabilities – meaning you can either use convenient pre-filled ink cartridges or draw bottled ink directly into the pen using the converter. This versatility makes it an excellent choice for beginners transitioning from disposable pens to refillable fountain pens, as well as for students, professionals, and calligraphy enthusiasts.

The brand name "CHREN传人" translates to "Chuan Ren" – which carries the meaning of "passing down" or "heritage," fitting for a writing instrument that encourages the traditional art of handwriting. The pen is manufactured by Zhejiang Lishui Chuanren Pen Industry Co., Ltd. , a Chinese company with several years of experience in the stationery manufacturing industry .

Key features from packaging:

  • 抽墨式双用钢笔 (Dual-use: Cartridge + Converter)

  • 乐派 / LOPEPEN (sub-brand or series name)

  • 铱金笔 (Iridium nib – durable and smooth)

  • Refillable – works with both cartridges and bottled ink

  • Smooth writing experience

  • Perfect for beginners and students

✅ Stub nibs (1.1mm, 1.5mm) – excellent for beginners interested in calligraphy.

6. Dual-Use Filling System – The Star Feature

This is the most important feature of the Chren fountain pen. Dual-use (抽墨式双用) means you have two ways to fill the pen:

Option 1: Ink Cartridge Refill (墨囊)

 
Cartridge Feature Details
Type Standard 3.4mm international cartridges 
Color options Blue, Black, Dark Blue 
Installation Push-fit – simply insert cartridge into the grip section
Convenience No mess, portable – carry extra cartridges
Availability Widely available; Chren brand cartridges are common

How to install a cartridge:

  1. Unscrew the pen barrel

  2. Remove the empty cartridge (if present) or converter

  3. Insert a new cartridge firmly into the grip section (narrow end first)

  4. You should hear/feel a slight "click" when properly seated

  5. Wait 1-2 minutes for ink to flow to the nib

Option 2: Ink Converter (抽墨器)

 
Converter Feature Details
Type Screw-type piston converter (included in many sets) 
Ink source Any bottled fountain pen ink
Economy Much cheaper per milliliter than cartridges
Eco-friendly Reduces plastic waste from disposable cartridges
Color selection Access to hundreds of ink colors (not limited to cartridge options)

How to use the converter:

  1. Attach the converter to the grip section (push and twist to secure)

  2. Dip the nib into bottled ink (submerge completely)

  3. Turn the converter knob to draw ink into the pen

  4. Wipe excess ink from the nib with a cloth

  5. Start writing!

✅ Best of both worlds – convenience of cartridges for travel, economy of bottled ink for home/office use.

7. Ink Cartridge Specifications – 3.4mm Standard

The Chren fountain pen uses 3.4mm diameter standard international cartridges .

 
Cartridge Spec Detail
Diameter 3.4mm (standard international size)
Length Standard (approximately 6-7 cm)
Material Plastic 
Color options Blue, Dark Blue, Black 
Packaging Bulk packs available (e.g., 100 pieces per bottle, 12 bottles per inner box) 
Safety EN-71-3 certified (safe for children's use) 

Compatibility note: The 3.4mm standard is widely used by many fountain pen brands, so you are not limited to Chren-branded cartridges. Other brands using the same standard should fit.

✅ Standard size – easy to find replacement cartridges.
✅ Safety certified – meets EU safety standards for children's products .

8. Heat Erasable (热可擦) Option

Some Chren fountain pen models feature heat-erasable ink (热可擦) .

 
Feature Details
Technology Thermo-sensitive ink
Erasing method Friction/rubbing generates heat, making ink disappear
Reappearance Ink may reappear in extreme cold (below freezing)
Best for Students, practice writing, homework corrections

Benefits of heat-erasable fountain pens:

  • Correct mistakes without using correction fluid or tape

  • Keeps work looking clean and professional

  • Great for students learning to write

Limitations:

  • Not for legal documents or permanent records

  • Ink may fade over time

  • Not waterproof

14. How to Maintain

  1. Clean every 4-6 weeks – flush with lukewarm water if using the same ink color.

  2. Clean when changing ink colors – always flush thoroughly between different ink colors to prevent mixing and clogging.

  3. Store horizontally or nib-up – prevents ink from pooling in the cap.

  4. Cap after use – prevents nib from drying out.

  5. Use quality ink – cheap, poor-quality ink can clog the feed.

  6. Don't share nibs – nibs conform to writing pressure; sharing can misalign.

Cleaning steps:

  1. Remove the cartridge or converter

  2. Flush the grip section with lukewarm water using a bulb syringe

  3. Let dry completely before reassembling

  4. If using a converter, draw water in and out to clean it
