Description This TWSBI Kai fountain pen features a gorgeous dark blue marbled acrylic resin, accented by rose gold-plated trim, and comes with a rose gold-plated stainless steel nib in a size similar to the TWSBI 580 nib. As with all TWSBI pens, it comes with a piston ink-filling mechanism and has all detachable parts. An ink window allows you to see your remaining ink level. The pen cap will physically fit onto the back of the pen body in a way that would be considered to be posting, but TWSBI recommends not doing so to avoid scratching the barrel. The TWSBI Kai fountain pen is a limited edition, and will have a short production run. Grab yours today! TWSBI believes that it is important to allow the user to disassemble and reassemble the pen, in order to completely experience the traditional aspects of owning and using a fountain pen. The TWSBI pen packaging includes a wrench and silicone grease. ** Please note that these accessories are not intended to be used immediately, as they are better used for long-term care and maintenance. In addition, please use extra care if you choose to disassemble the pen, as breakage or cracking could occur if done incorrectly. Please note that Pre-Sales begin October 2, and shipping begins on October 4.
