From Nadine’s (the designer page), I quote:
“Pencils made from the carbon of human cremains. 240 pencils can be made from an average body of ash – a lifetime supply of pencils for those left behind.
Each pencil is foil stamped with the name of the person. Only one pencil can be removed at a time, it is then sharpened back into the box causing the sharpenings to occupy the space of the used pencils. Over time the pencil box fills with sharpenings – a new ash, transforming it into an urn. The window acts as a timeline, showing you the amount of pencils left as time goes by.”
