Yes they are Vapor atomizers. Disposable tanks. One of These tanks can last up to 1 month without burning up before you have to switch to a new one. I have used this type of atomizer since last January and never had a problem.
Yes but they are only the tops. You will have to have the batteries for these. They are excellent, i just have way too many right now. I switched to a higher end product recently and do not use the disposable ones as much. These will each ladt you close to a month if you dont just constantly have your vape in your mouth. :)
