The PRIMO REGOLARE product line includes rulers, set squares and protractors. Graphite pencils in different grades, a blister of erasers and some pens, in three or 10 colours, complete the range. PRIMO REGOLARE is ideal for school. PRIMO technical articles are available in different formats. They are made of polystyrene, resistant and safe. They have an inking edge and embossed graduations to improve precision, they are very long lasting and their anti-reflective smoky gray tone facilitates reading. Design and production are made in Italy. Graphite pencils of different grades are suitable for technical and artistic drawing, and so are PRIMO pens as well: with them, you can simply write or create colourful drawings. A soft eraser will erase only what really needs to go.
