Innovative, extruded wood-cased pencils are made of a natural fiber consisting of 70 percent wood for top-quality writing, drawing and sketching. This material called WOPEX (Wood Pencil Extrusion) offers a significantly higher utilization of wood per tree so this eco-friendly pencil uses fewer trees, creates less waste and is manufactured using PEF-certified wood from sustainably managed German forests. The production procedure is completely solvent-free. Innovative, homogenous WOPEX material ensures exceptionally smooth and even sharpening results with any quality sharpener. WOPEX HB No. 2 pencils write twice the length of a standard pencil and feature latex-free, PVC-free erasers.
