Enjoy beverages of all types under the stars in our Starry Nights drinkware collection. Part of the “Lights Out” line of glow-in-the-dark glassware, this design has cosmic swirls that glow in the dark above a base of tropical color. To achieve the glow, simply allow light of any kind (lamp or sun) to shine on the glass. Then when it is placed in a dark setting, it will glow! Make your nighttime patio or pool party an affair to remember. The color never fades and is nontoxic. You can chill your glassware, too. Designed for cold beverages only. Handwashing recommended. Collection includes Pitcher, Tumbler, Beer/Root Beer Mug, Rocks/Juice Glass, Water Goblet, Shot Glass, Cordial Glass.
