It features a round 4mm nib and a pump-action valve that delivers consistent, opaque paint flow with minimal waste. The PX-20 uses an oil-based paint formula that bonds permanently to glass, metal, plastic, ceramics, stone, and wood. A go-to choice for artists, crafters, and writers who need precision rather than coverage.
