The TWSBI Kai, a limited edition acrylic resin fountain pen featuring a piston-filling mechanism and rose gold plated trim.
- Part of TWSBI’s series of limited production acrylic resin fountain pens, such as past year’s Draco and Aurora models.
- Not intended to be posted (the cap could scratch the barrel).
- Rose gold plating on all trim, including on the stainless steel nib.
- Piston-filling mechanism holds significant amounts of ink inside the pen, so no converters necessary - just a bottle of ink!
