Sprout® pencil is the first pencil that you can plant and grow, and it is 100% biodegradable. Made of birch wood, at the top of the pencil there is a biodegradable capsule containing non-GMO seeds, which germinate in contact with water. Growing the Sprout® Pencil is super easy. When the pencil becomes too short to be used, plant it in a pot and assure it gets plenty of water and light. In a few weeks, the first seedlings will sprout!
