Product Information

There is no need to sharpen the pencil, so as long as you regularly refill it, you have a pencil that is ready to use at all times - at school, in the office and on the go! Made of a combination of pigment and waxes, it's fully waterproof and can be rubbed off easily with a dry cloth.

The clay acts as a binding agent and gives the lead its shape and strength, while graphite produces the characteristic silvery black colour on the page.

These Chinagraph Pencils are p erfect for writing or drawing on most surfaces, including glass, china and acetate. Other types are covered in paper and sharpened by pulling a string to peel off the paper, needing no additional tools to remain functional. However, there are further differentiations in the hardness grades H and B, which are determined by a number placed in front of the letter. As the lead is still very soft and bendy at this point, it has to be baked in the oven at a very high temperature. No matter what you use a pencil for - for drawing or writing - a sharp lead is required at all times.More recently, it has been produced in propelling form, essentially similar to a mechanical pencil, this type in particular being associated with knee boards employed by NATO aircrew. Professional and amateur artists use them for drawing and sketching, but pencils can really be used for just about anything and by any age group. citation needed] Marks made by grease pencils are resistant to moisture and can usually be removed by rubbing the marked surface with a paper towel.
