This Kaweco Mini Foldable Converter allows for the use of bottled inks with Kaweco Sport and Liliput fountain pens. It works by fitting into the pen as normal and then folding the piston over. This allows the converter to fit inside the pen's barrel and hold the same amount of ink as the non-folding converter.

• capacity 0.43cc approx
• fits both Kaweco Sport & Liliput fountain pens
