Heat Pad Pencil by Chihiro Kuuno & Kenjo Ohashi

Heat pad pencil
Designers Chihiro Konno and Kenjo Ohashi have designed a heat pad pencil, a bamboo pencil set and small heating pad, conceived in the spirit of sustainable energy and production.
The heating pad contains bamboo shavings by means of the user sharpening his/her pencil. When the bamboo chips are enclosed within the satchel, they begin to ferment and the remains produce an average temperature of 50 degrees celsius for a duration of 2-3 years. After the period of heat has ended, the matter held within the heating pad may then be used as plant fertilizer, in its composted form.
