### ⭐⭐⭐⭐⭐ Best pen for the money
*by W***N on March 29, 2026*

The best cheap pen I own. Writes beautifully, massive ink reservoir lets you write forever, and you can take it completely apart for cleaning and maintenance. I haven't seen a better pen at this price point.

### ⭐⭐⭐⭐⭐ Best entry level fountain pen - EVER!
*by K***E on September 22, 2024*

Out of the box, easy to fill, easy to clean, and quick to write. Great fill capacity. Works with a variety of inks, and glides so smoothly across the paper. I recommend Tomoe River paper. Dries relatively quickly. Great packaging. I’m so pleased with these pens. Great for beginners! Worth every penny.

### ⭐⭐⭐⭐⭐ Unbelievably excellent!
*by M***E on February 24, 2023*

Rock solid construction and crystal clear. I initially bought a competitor's model for ten dollars less and it was absolute junk. I bought this as a replacement and it is light years better! Pen comes with a dissasembly wrench and silicon oil bottle for the piston. Construction quality is flawless. Writes like a dream. Nib is not flexy if that's what you're looking for. 110% recommended!! Update: Carried it around in a scrub shirt pocket at work - a bit risky! But no leaks so far! The nib's small, round tip allows for smooth lines in most directions. Pen can write at high and low grip angles too! The nib will flex the tiniest amount when moving from light pressure to heavy pressure. The line will get about one third wider, but that's leaning on it a bit! Absolutely no feed issues with Noodlers 'Heart of Darkness' ink. Love it as an everyday writer and doodling tool! I'll absolutely pursue getting a second TWSBI ECO T, either with a factory flex nib, or installing one myself. The standard one I already have just writes too well to change it up!
