## Customer Reviews

### ⭐⭐⭐⭐⭐ Majohn Delivers Highend Quality, at Entry Level Price.
*by A***R on April 21, 2025*

Anyone who missed out on the dolce vita and the Hemingway should give this pen with a number 8 nib a chance, you will be seriously impressed with this modern interpretation of a classic fountain pen style! It’s not just a well executed style, but mine was well tuned and writes beautifully, a nib that I don’t have to tune is a rarity even with brands like Pelikan, Kaweco, and really most that don’t get tuned by retailers after production, so this level of quality control at all levels of the pen, impress me as a fountain pen user and collector of over 2 decades. This pen punches well above its price!

### ⭐⭐⭐⭐ Great nib, garish body
*by A***N on May 28, 2025*

The good—the nib is lovely and smooth and the pen has a nice heavy weight that makes it easy to write with without being heavy-handed, posting changes the center of gravity in such a way as to make the pen feel lighter in the hand so there is some versatility for users preferring something a bit less weighty, the piston operates smoothly but I did find it needed to be left just slightly open to keep up with the #8 nib so I didn’t have dry starts.The bad—despite all the good points, I wouldn’t have bought this pen if I had seen it in person-the barrel isn’t white as the product pictures led me to believe, it’s glittery and the pattern on the band isn’t as refined in person as it is in the photos.I will use this pen for all it’s good qualities, I just wish it didn’t look like it was made for the unicorns and rainbows crowd.

### ⭐⭐⭐⭐⭐ Excellent value
*by M***Y on June 19, 2025*

Why did you pick this product vs others?:Saw this on YouTube with favorable review - and was pleasantly surprised at the quality of the pen. Smooth nib that writes exceptionally well
