ZETA Water-Activated Light-Up Tumbler – Red Bull Edition

Add water and watch the cup come alive. Two bright light points activate from the base, creating an uneven glowing effect through the drink instead of a flat single-color light.

• Water-activated internal lighting

• Two stronger light zones with a natural color gradient

• Transparent acrylic tumbler with glitter finish

• Clear fitted lid and reusable metal straw

• Available in Cyan, Pearl Blush, Blue, and Candy Pink

The cup is shown switched off in the main group photo. Individual color photos show the water-activated lighting effect.
