Studded Glow in the Dark Tumbler

Luminous double wall studded glow in the dark tumbler with a blank circle to have it personalized to your liking. In order for the glow to work the tumbler needs to absorb UV/ Sun lighting, the glow will last longer per the manufacture can last up to 12 hours in the dark depending on the total light it observes. Same feel as the Starbucks but off-brand tumblers. BPA free and should not be put in the dish washer or microwave. Hand wash only is highly recommended.
