Brand Nataraj Superior Bonded Lead-Free Natraj Plasto Eraser And Natraj Sharpener. We do not use any forest wood for manufacturing pencils. Our concern for the environment has led us to develop our own plantations. Moreover, we procure wood from the farmers who either grow trees on their farm, land, or in the courtyard of their residential premises. This practice ensures an uninterrupted supply of wood of consistent quality. It also helps protect biodiversity and maintain ecological balance. Constant efforts are made by the company in improving processes and maximizing utilization of inputs to prevent degradation of the environment. All ingredients used by the company are non-toxic in nature. Research & Development efforts are also being made to switch over to eco-friendly water-based lacquers and PVC-free formulations.
