These clever pencils give new meaning to sustainability. Once your pencil gets too short to use, just plant it upside down in soil. Give it a bit of sunlight and water, and the seeds in the top of the pencil will begin to sprout. Each pencil in the set contains a different type of seed. Grow chilli, coriander, fenugreek, mustard, and tomato. The pencils themselves are made from 100% recycled news paper.  How does it come? Contains 5 HB pencils in a cardboard sleeve. Sleeve is 27 x 11 x 1 cm at widest part.
