The Castle Art pencil sports a striking 7mm Black Matt finish barrel, held safely within the barrel is an exciting 3.8mm core bursting with generous levels of pigment. On the end of every Castle Art pencil is a 1 and 1/4 inch pigment identifier, clearly making the pigment within that particular pencil, which also makes pigment selection visually a pleasure. Separating the Black Matt barrel and the pigment identifier is a painted silver ring.
