The Perpetua Lumina was created specifically for children and adults who work in dark conditions. The pencil's eraser attracts and stores natural and artificial light during the day, releasing it in the dark.

It is an eco-friendly pencil, suitable for all ages, made from 80% recycled graphite that would otherwise end up underground. It is non-toxic, does not stain the hands, does not break, and features a flat side that prevents it from rolling and falling off the desk.
