## About this gift

Seven LED lights give this Oslo pebble aroma diffuser its colour change glow, for anyone who likes essential oil fragrance at home. An aroma diffuser turns water and essential oil into a fragrant mist.

Ultrasonic waves vaporise the water and essential oil in the tank into a cool, dry fragrant mist. The tank holds 400 ml, and the timer runs for 3 to 6 hours. It switches itself off when the water runs out. It is powered by USB through a 100 cm cord. The plastic body stands 9.5 cm tall with a 13.5 cm diameter and weighs 330 g.

With a timer and automatic power off, this USB diffuser is a straightforward first aroma diffuser, or a gift for a friend who likes to scent a room with essential oils.
