Create an eerie, magical atmosphere with these ultrasonic mist makers! This 4-pack lets you set up multiple fog zones for Halloween, parties, or home decor. Just place them in water (about 5-7cm deep), plug them in, and watch as they produce thick, rolling fog. Each unit has 12 colorful LED lights that cycle through different hues, adding a spooky glow. They include splash guards to minimize water spray and are designed to automatically shut off if the water level gets too low. They work on 110-240V power, so they're versatile for indoor or outdoor use. Perfect for Halloween displays, Christmas villages, pond fog effects, or even indoor water features. Transform your space into a misty wonderland—easy, safe, and super fun!
