Description The TWSBI Vac Mini fountain pen in Smoke is a departure from the piston filler fountain pens found in the rest of the TWSBI lineup. The TWSBI Vac Mini fountain pen has a clear acrylic body, which makes checking the level of your ink a breeze, accented by a black grip section and turning knob. The smooth writing steel nib, silver clip and trim accents make this pen a real workhorse! The Vac Mini fountain pen is slightly shorter than the Vac 700 fountain pen, and features a few design changes that you will love! Additional replacement TWSBI Vac Mini nib units are available in several nib sizes. Please make sure to choose the Vac Mini nibs, and not another model. This vacuum filler pen holds a LARGE amount of ink, and fills by unscrewing the end cap, pulling it out, and then the pen fills on the downstroke. Be sure to hold the pen in the ink for several seconds after pushing the end cap in, and for best results, you should do this twice. The TWSBI Vac Mini fountain pen fills with bottled ink only, and for best filling results, the TWSBI Vac 20A ink bottle is a wonderful option. 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.
