The core of a Holbein coloured pencil is made of a mix of pigments, wax, oil and fats. This unique composition provides colouring pencils with great qualities. A Holbein pencil is creamy, but not too soft or hard. In terms of hardness, the pencils are just in between the Polychromos and Prisma pencils. The pigment in the pencils is beautiful and powerful, even in the softer pastel colours. They colour wonderfully on paper and blend well. You can also use a Holbein pencil in combination with other colouring pencils. Note: due to the unique Holbein composition, they do not blend well with other brands.
The pencils are well lightfast, and the degree is indicated on each pencil. The centre of the coloured pencils has a diameter of 3.8 mm, the pencil itself has a diameter of 7.8 mm.
