On a cold day when a room temperature is 15C, the metallic cap of a pen becomes much colder than its plastic body, though both are at the same temperature of 15C, because

metals have higher thermal capacity than plastics

plastics have a lower density than metals

plastics have a higher thermal conductivity than metals

metals are good conductor of heat
