XUIIOSOOKP 6 Rolls Glow in The Dark Tapes, 5m/16 ft Luminous Neon Fluorescent U

Glow in Dark AFTER Absorbing Light: Neon tape itself does NOT emit light, but will produce an amazing luminous effect WHEN ILLUMINATED BY ULTRAVIOLET RAYS OR BLACK LIGHT. The stronger the light absorption, the better the luminous effect in the dark.
