Liquid-Activated Glow Feature - The LED lights automatically flash and change vibrant colors once liquid is poured into the glass, creating a magical glowing effect in the dark. Lights turn off automatically when empty, making them perfect for night parties, bars, and festive events.

Exquisite Crystal Cut Design - Crafted with a classic diamond-cut pattern, the clear tumbler refracts light beautifully, enhancing the colorful LED glow and adding an elegant touch to any drinkware collection. The curved silhouette fits comfortably in your hand for easy sipping.

Replaceable & Long-Lasting Batteries - Powered by a 3V lithium battery, the LED base is designed with a twist-open compartment (coin-operated for easy opening) for simple battery replacement. The included battery provides hours of glowing use, and replacement batteries are widely available.

Safe & Durable for All Drinks - Made of high-quality food-grade transparent acrylic, these light-up cups are non-toxic, shatterproof, and safe for serving whiskey, cocktails, beer, juice, and more. The smooth surface is easy to rinse clean for repeated use.

Versatile Party Essential - Ideal for Halloween, Christmas, birthdays, weddings, bachelor parties, nightclubs, bars, and poolside events. They also make fun novelty gifts or decorative night lights for home bars, adding a lively, festive atmosphere to any gathering.
