The pencils have perfect ergonomics thanks to the triangular shape which is really comfortable to hold in the hand. They come supplied in the practical and stylish stand-up Staedtler box. With the Staedtler box you simply open, stand it up and start writing. The unique Staedtler box is so practical and just as ecologically efficient: Without the need for additional external packaging, it serves as a practical storage box and clever pencil holder at the same time. The box includes 12 brilliant assorted colours. The lead is soft and break-resistant and has a diameter of 3mm. There is a 'name box' on each pencil so the owner can add their name for easy identification. The pencils are easy to sharpen with any quality sharpener. These pencils have the Staedtler 'ABS feature'. Especially with children, coloured pencils have to be able to stand up to a lot of punishment: The unique Anti-Break-System (ABS for short) increases their service life. Because the richly coloured, high-quality lead core in our coloured pencils with ABS is surrounded by a unique white protective coating. It is so hard and resistant that the break-resistance of the coloured lead is increased by up to 50%, making the pencil up to 30% stronger.
