This is a set of four LAMY Safari fountain pens, a collaboration model with Harry Potter. The nib size is EF (Extra Fine). Each pen features a special design with colors inspired by the Hogwarts houses, along with their emblems and house names. While typical Safari limited editions only have exterior changes, this is a rare limited edition with engraved nibs. These pens can be purchased individually, but this set comes in a special presentation box exclusive to the 4-pen set. The pen bodies are in pristine condition, as they have never been touched since being purchased new. For an additional 500 yen per pen, I can include a LAMY genuine converter (LZ28). Please leave a comment or request a combined purchase with the converter listing. I have other pens for sale as well. Please take a look. → #Lamypen
