Opus 88. These pens are all handmade in Taiwan, including the Urushi by Artist Lishu Huang. Its a brand that is not really anywhere in the states. The pens come with my guarantee of quality as well as any nib issues will be supported by Mike It Work. Nib customization will also be available with a max 2 week turn around including shipping to Mike and back. Most of the time its faster, but this gives some room. For any nib grinding, please add $40 to the price.
