FAQs
How does the glow-in-the-dark finish work?
How does the glow-in-the-dark finish work?
Place the tumbler under bright sunlight or indoor light to “charge” the glow. The brighter and longer the exposure, the stronger it will glow in the dark.

Testimonials
- “I was mostly buying this because of the Sally and Jack design, so the glow-in-the-dark part felt like a fun bonus. It actually surprised me when I turned the lights off. The whole cup gives off this bright green glow and the artwork still shows through really well. I’ve been taking it to work every day, and the handle makes the larger size easy to carry.” Marissa T.
- “This was supposed to be an early Halloween gift for my sister, but I ended up ordering another one for myself after opening the package. The colors are really pretty in daylight, especially the purple details around the top. At night it has a completely different spooky look. It feels much more special than a plain tumbler and definitely gets people asking where it came from.”Dana K.
- “I’m picky about character tumblers because some of them look great online and then feel cheaply printed in person. This one looks much better than I expected. The design is detailed, the cup feels sturdy, and the 40 oz size means I’m not constantly refilling it. I charged the glow near a bright window and it lit up really nicely later that evening. It’s become my favorite cup for fall.”Steph R.
