Cleo Messograf Pen

Cleo Messograf is a legendary pen. A chrome-plated, solid brass, retractable ballpoint that's also a ruler, a calliper gauge with vernier scale, a thread scale and a tyre tread gauge. A beautifully-made little item that's also impressively practical.

The vernier gauge is capable of measuring up to 90mm with a tenth of a millimetre accuracy.

Uses standard Parker-style ballpoint refill. Supplied with a black refill.

For the ultimate pen, add a Schmidt P950 Megaline pressurised refill for writing upside-down, on damp paper and in low temperatures.

Supplied in a card gift box with instruction leaflet.
