Many graphite and coloured pencil artists use pencil lengtheners to get more use out of their pencil stubs. The Caran d'Ache Pencil Lengthener is made from metal and is a glossy red colour. It is designed to fit hexagonal and round pencils with a small diameter such as Cretacolor Charcoal Pencils or Staedtler pencils. Suitable for Caran d'Ache ranges - Supracolour, Pablo and Prismalo. Simply push the lengthener onto the end of the pencil. This Pencil Lengthener measures 5 inches and is hollow, so that it is easy to dislodge extremely small stubs, should they get stuck.
