USB Bottle Humidifier Mini is a beautifully harmonious fusion of precision engineering with the prestige of 11+ design aesthetics. Everything down to the aluminum cap is meticulously refined to ensure that even the slightest details are of the highest quality. The surface of the bottle has been elaborately constructed to look as transparent as possible, and feel as heavy as glass without the concern of cracking or shattering. The USB Bottle Humidifier Mini's compact size is no way an indicator of its ability as a humidifier. Needing only USB for power, the humidifier is powerful enough to supply sufficient humidity for any personal space, whether it be the bedroom, office, or living room.
