0.5mm
Very fine point
A measurement of half a millimeter, commonly used to specify the tip size of mechanical pencils and pens: I prefer a 0.5mm pencil for detailed work.
The designation appears on office supplies, lead refills, and technical drawing instruments, distinguishing finer points from thicker options like 0.7mm or 0.9mm.
