Designed by Hideyuki Kumagai, the leaf thermometer will stay its natural green color when the room temperature is moderate (20-25‹C (68-77‹F). Below 20‹C, the leaf will turn brown (indicative of chilly, winter weather but above 25‹C, the leaf will turn yellow, like a ray of sunshine. They come in either a 5-pack of large leaves or an 8-pack of small leaves so they can be placed strategically around your home or office so, at-a-glance, you can manage your domain. Or create a wall mural that changes with the seasons. Smart!
