Inside: CENTO3.E, a multifunction instrument for graphite, crayon and highlighter inserts; CENTO3.G, a pocket fountain pen; and CENTO3.O, a mechanical pencil for precise technical drawing. Every instrument is 3D-printed in biodegradable graphene PLA, one at a time, which leaves a subtle non-slip texture, and the three-lobed section keeps it from rolling off the table. The set also holds three graphite leads, blue and red write-on-anything wax crayons and green and yellow dry highlighters, presented in a handmade 9.8″ × 9.8″ box covered in soft-touch paper, with the story of the project in Italian and English.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e EGOUNDESIGN (Bologna, Italy)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollection:\u003c\/strong\u003e CENTO3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesign:\u003c\/strong\u003e Achille Castiglioni and Gianfranco Cavaglià, 2001; produced by EGOUNDESIGN since 2021\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSet:\u003c\/strong\u003e CENTO3.E multifunction instrument, CENTO3.G pocket fountain pen, CENTO3.O mechanical pencil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRefills included:\u003c\/strong\u003e 3 graphite leads, 2 write-on-anything wax crayons (blue, red), 2 dry highlighter wax crayons (green, yellow)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 3D-printed biodegradable graphene PLA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBox:\u003c\/strong\u003e 9.8″ × 9.8″ × 1″ (250 × 250 × 30 mm), handmade, soft-touch paper cover\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlso included:\u003c\/strong\u003e CENTO3 project description in Italian and English\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackaging:\u003c\/strong\u003e Gift boxed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMade in:\u003c\/strong\u003e Italy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem number (MPN):\u003c\/strong\u003e EM-TC3-TRIOSET\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAll three CENTO3 instruments: multifunction, pocket fountain pen, mechanical pencil\u003c\/li\u003e\n\u003cli\u003eThree-lobed ergonomic section that won’t roll\u003c\/li\u003e\n\u003cli\u003e3D-printed in biodegradable graphene PLA, made in Italy\u003c\/li\u003e\n\u003cli\u003eGraphite leads, wax crayons and highlighters included\u003c\/li\u003e\n\u003cli\u003eHandmade soft-touch presentation box with the project story\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eBest for\u003c\/h3\u003e\n\u003cp\u003eA desk set for an architect, designer or writer; a milestone gift for a graduation, a new studio or a retirement; a collector of Castiglioni’s lamps and furniture.
