This nano mister is what we use in our salon and after many requests by our customers wanting the same product, we decided to bring them in for sale. This Nano mister charges by a USB port making it efficient for use, as it does not require batteries. It holds 0.67 fluid ounces of tap water and runs up to 12 hours per charge. They are 4.5″  x 1.25″ in size thus making them compact for your tray or drawer. We also love how cute they look
