45 different shades of the tried and trusted Bruynzeel quality colour pencils. The pencils are made of high quality pigments, which results in a nice colour output and makes them easy to mix with each other. The core measuring 2.9 mm ensures extra-long colouring pleasure. All Bruynzeel pencils are gluten-free and are made with care from responsibly-sourced wood. Bruynzeel pencils are also double-glued, so that they are extra strong and the chance of the colour core breaking - for example, if the pencil falls to the ground - is minimal! This prevents broken points and ensures that you rarely need to sharpen the pencil.
