Wacca is the Japanese word for Circle. When the WACCA AROMA DIFFUSER is switched on, elegant ring-shaped puffs are released to subtlety diffuse aromatic scent into the room. The concept is based on the idea that the enjoyment of scent is enhanced not only by the sensation of the aroma but also by the visual experience. The WACCA has two modes. By simply pushing the control button twice, the steam is released in a continuous flow to bring even more humidity to the room. With the vaporizing system of the WACCA, the steam is released at a safe temperature and the unique shape of the WACCA puff evokes a friendly, personal feeling.
