This compact flashlight is designed with a hexagonal cylinder to keep it from rolling away on you. 8 bright purple UV blacklight LEDs will let you make white cotton and glow-in-the-dark items light up like crazy, or use it to check IDs, money, radiator/transmission leaks, or pet stains. Useful out in the field too for checking minerals or looking out for scorpions. Made of durable metal. Uses 3 AAA batteries (included). Comes with a FREE carrying pouch!
