These cool arc reactor coasters are officially-licensed Marvel merchandise. They come wholly-inspired by the latest design of the arc, as seen in the third installment of the movie franchise, Iron Man 3. The coasters come as a set of four and are made from plastic and aluminum only (no palladium, guaranteed). Blue LEDs light up the arcs like in the film, and are powered by 2 CR2032 batteries (included; 8 in total). Power switch can be found at the bottom, along with rubber feet stoppers for stability. Protect your precious table as the Avengers would the earth. Measures 3.75 inches in diameter.
