Just like a normal pencil, but when it becomes too short to write or colour with, just plant the pencil into some soil then watch it grow! 

At the end of each pencil, you’ll find a water-soluble seed capsule (instead of an eraser) that can be planted in soil.  

Available in a choice of 10 seeds (sunflower, daisy, carnation, forget me not, cherry tomato, basil, thyme, sage, coriander and chia).
