The TWSBI Mini comes with a benchmark piston ink-filling mechanism and has all detachable parts. Like many other TWSBI fountain pens, it features a demonstrator clear acrylic body so you can see your ink level, and a clear cap. About one inch shorter than the Diamond 580, the Mini is conveniently pocket sized, with a cap that can be screwed onto the back end of the barrel when the pen is being used. Its faceted barrel catches light and makes your ink shine, and it also helps keep the pen from rolling away. The piston filling mechanism is easily operated by twisting the knob at the end of the barrel counter-clockwise to extend the piston, submerging the nib in ink, then screwing the knob tight to retract the piston, drawing ink into the pen straight from the bottle—no need for cartridges or a converter! Be careful, operating the piston while ink is in the pen will cause ink to leak out of the pen.
The pen comes in an attractive clear plastic case with a clean, modern design. For protection, the plastic case is packaged in a cardboard box.
