Schmidt Megaline Refills are gas-pressurised, giving them 'space-pen' properties - they write upside-down; in zero gravity; underwater; and in extreme temperatures.
The P950M is Parker format and will fit a wide range of ballpens. The 620M is 'D1' format and fits a huge range of compact, pocket and multifunction pens. The 4889M refills Fisher Space Pens and Spacetec pens. |
