TWSBI Piston Converter
TWSBI Piston Converter is backordered and will ship as soon as it is back in stock.
Standard International top hole fitting. Holds more ink than the typical converter.
Fits the TWSBI SWIPE fountain pen, as well as other fountain pens that can take an International Standard converter.
Traditional piston twist mechanism.
Please Note: The shoulder of this converter is quite wide, so this may not fit an International Standard size fountain pen that has a slim barrel.
