With the NEBO GLOW Light-Up Tumbler Handle, you’ll always have a convenient light in your hand. This mug light is perfect for those early mornings when you’re prepping for a weekend camping trip. Simply slide your tumbler in this cup lamp, and you have an easy-to-hold handle for your mug. Additionally, the base of the GLOW acts as a light-up handle, so you get a mug flashlight as well. This convenient device fits 20- and 30-ounce tumblers, so you can change it between different travel mugs. Plus, you can choose between three light modes depending on how much brightness you need. There’s a 220-lumen task light and a 130-lumen lantern light, both of which can last for three hours. If you use them together, the light lasts for two hours—plenty of time to get the job done.
