One of a kind, will not be remade, novelty 20oz tumbler. This tumbler is completely safe to use for hot and cold but will not have the same properties in the long hours that normal stainless tumblers do.
Battery pack is hidden in the bottom of the screw on cap. Care will have to be taken to not get that area wet. Battery is replaceable when it runs out. Lights have three on modes. Message me if you like a video of the cup before purchasing. Tree is 3D and will not be 100% smooth.
