Doko Demo Vape No. 1 Mirai, unopened. I'm selling it because I don't use it. It can be used for 20 days with a usage of 6 hours a day (approximately 120 hours). Instant purchase is welcome. Since it is unopened, I have not confirmed its operation. Batteries are included, but I recommend using new ones. Please purchase after understanding the above. Please refrain from purchasing if you are nervous about the condition.
