Fire Extinguisher” – 4″ x 18″ Glow In Dark

Product Description

Glow In The Dark self-adhesive signs will glow for up to 8 hours at a time after darkness occurs but are very visible in normal lighting. Cycling from light to darkness does not wear out the sign. DO NOT USE HOUSEHOLD CLEANER to clean Glow In The Dark Signs, as it will cause the printing to run.
