Also included is a LED lighted plastic base that uses color shifting lights to create the illusion of a pulsing motion. Comes gift boxed with a 3" crystal sphere, a 2 3/4" square by 1" high crystal stand, and a 2 1/4" tall lighted stand with USB/AC adapter. Also runs on 3 AAA batteries (not included).
