Posca Extra Fine (Poly Tip) 1M
The Extra Fine is a poly tipped Posca that has a nib made of fibres rather than the normal felt nib. They are very popular for finer detailed work. The nibs produce a line with a width of approx 1mm. These nibs aren’t subject to residue build-up like the steel tipped ultrafine but the line thickness can vary due to the fibres of the nib working like a brush rather than a fixed nib.
