China Graph Pencils

China graph pencils (also known as grease pencils or wax pencils) are an writing item made from hardened parafin wax which can mark on a variety of surfaces such as: hard, glossy non-porous surfaces such as porcelain, glass, polished stone, plastic, ceramics and other glazed, lacquered or polished surfaces, as well as the glossy paper. These pencils are particularly useful in the mining sector where marking on rough surfaces such as core samples or on waterproof glossy paper are needed. China graph markers are supplied in a box of 12 and are available in variety of colours, see below.
