This is the coolest of cool tumblers with light functions in the lid and base.
A fun, double walled, light up drinking cup with a clear removable straw and screw top lid. Use the soft touch button on the lid to chose from 8 different lighting modes. The base button has 4 independent light functions – strobing, flashing, static and off, flashing in colour from red to blue to green. You can make extra cold icy drinks by placing the tumbler in the freezer - and look even cooler!
