Keep it in your bag, and steam anytime, anywhere, as long as you have water! It's a great item! Perfect for the season when dryness is a concern♪ The design is simple and cute, and it comes with a mirror! You can also touch up your lipstick, lol. There are no instructions, but it's simple, so you'll probably figure out how to use it right away. The box is slightly torn. Please be aware of this. ☺︎ I have never carried it with water in it, and I don't recommend it because it might leak. It can be charged via USB. I plan to waterproof it with plastic and ship it via Yu-Packet Post. ☺︎ Thank you.
