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

Plastics have a lower density than metals
Metals have higher thermal capacity than plastics
Metals are good conductors of heat
Plastics have a higher thermal conductivity than metals
