WANCHER Kaleido Fountain Pen Aoumi (Blue Abyss) Stainless Steel Soft F Nib. This is the Aoumi color, commemorating WANCHER's 14th anniversary. As the name suggests, the barrel has a beautiful black and blue gradation reminiscent of deep water. The nib is stainless steel soft F. I inked it once with Iroshizuku ink for testing. After that, I lightly cleaned it and stored it. A QR code is printed on the inside of the box lid, which leads to the instruction manual, etc. It will be shipped with water damage protection.
