Art Alternatives - Portaminas 2mm con IndicadorLead holders are an innovative tool that allows you to draw with the feel of a wooden pencil without the hassle of sharpening or the inevitable downgrade to a stubby, hard to use nub. This lead holder is preloaded with one 2mm lead, which can be switched out with any standard 2mm leads. A three pronged vice holds the lead securely and releases it easily by depressing the barrel end.
