Nightmare Before Christmas Glow in the Dark Tumbler. Personalize it!

Personalize it! Glow tumblers need to be "charged" in sunlight or direct light for 2-4 minutes to activate the glow. The longer the charge, the longer the glow. The regular colors are vivid and gorgeous. 20 oz. Skinny Stainless Steel Tumbler. Features double-wall vacuum insulation (hot/cold) with a clear sliding lid, and straw. The tumbler fits most standard cup holders. It is 2X heat & cold-resistant compared to a normal travel mug and is BPA and lead-free. Made from 18/8 gauge stainless steel (18% chromium/8% nickel).
