Our pencils are produced using genuine lime tree timber. This relatively soft hardwood can be sharpened very well and offers an optimal combination of stability and flexibility.

The pencil leads are produced by burning of a mixture of clay (as a binding agent) and graphite. The hardness of a lead arises from the mixed proportions of these materials. The more graphite, the softer the lead.

Our pencils are normally supplied with a medium hard lead (HB). On request, we can supply other hardness grades. Our special-purpose pencils have leads with special addittives, allowing their individual use on shiny, damp or even porous surfaces, as required.
