12 colour pencils in a tin. These colour pencils are must-haves for every school bag! The core of the pencils is made of high quality pigments, which gives them a good colour output. Ideal for use during subjects such as drawing, mathematics or biology. The pencils are stored in a compact container, making them easy to carry. Gluten-free. All Bruynzeel pencils are carefully made from responsibly sourced wood. Bruynzeel pencils are also double-glued so that they are extra strong and the chance of the 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.
