Battery operated light up tumbler (battery compartment is on the bottom for easy access to replace batteries as needed). Tumbler can be turned on with on/off switch located on bottom of tumbler.
Please note that this tumbler will have raised areas where the lights are as this takes more epoxy to create than a regular epoxy tumbler.
