Sailor Fountain Pen TU-ZU Medium nib. I've used it a few times, and since I don't use medium nibs as often, I'm selling it. Both the nib and converter have been cleaned, but it has been used once, so please understand that it is a used item before purchasing. There is no outer box. It will be shipped in a water-resistant PP bag and wrapped in packing material. This is a fountain pen from the new writing instrument brand [TUZU], where you can find the writing experience that suits you. [TUZU ADJUST Fountain Pen] Adjust the nib by turning it. A fountain pen that adjusts to your own angle. Quoted from the website - Color: Green - Design: Cap type - Nib shape: Medium
