Don’t throw away your pencil stumps, extend the life of your pencil by using the Lyra pencil lengthener. This clever little tool will lengthen your pencil and give you hours or extra use; just prop your pencil into the metal clasp, slide the locking bar and you’ve now got a full length pencil again! Ideal for hexagonal or triangular thick pencils (both coloured and graphite) with a diameter of 10 mm, or thin pencils with a diameter of 7 mm.
