Make a big impression with the eye catching, novelty look of this huge purple LED gem. These light up promos feature a gray plastic open end band that comfortably fits most. An on/off button located on the bottom of the gem activates three light functions: a still light, a flash of each LED color at a time or a blinking setting that uses all LEDs at once. From fundraisers to corporate parties to bar promotions, these rings are a great way to put your brand directly in their hands.
