Panasonic Pocket Mist. This pocket-sized device is easy to carry around and use with the push of a button. The handy type produces a mist of approximately 40μm, effectively moisturizing even the back of your throat. It can be used for about 3 minutes when full (12ml). Refilling is, of course, easy. Requires 2 AAA alkaline batteries (Batteries are not included, please purchase separately.) How about it for various uses? In the dry season when colds are prevalent, for children in school, during breaks in meetings or sales activities, or as a companion during travel or business trips. Although it is new and unused, there is some damage to the packaging due to storage, please understand. This item is stored at home, so please consider this before purchasing. Thank you for your consideration.
