The mammoth can be restored… when you put the kit in a refrigerator! A new type of plastic model kit experience is here, enabled by an intricate skeletal structure and thermochromic resin! Exploring Lab Nature is a new product line that aims to offer an experience where users can learn more about a subject matter through building it! The mammoth from the new Exploring Lab Nature series is made of special molding materials that gain color when the temperature drops below 10 degrees C or 50 degrees F. After assembling the skeleton in the "Excavation Phase," the hide parts can be attached in the Restoration Phase. This plastic model kit offers a new experience where the attached hide parts change color when they are cooled down in a refrigerator to simulate mammoths that once lived in the frigid ice age.
