V4L's store. They have a room with all these filled cartos. They give you an 808 to use to vape them. I tried 20 - 30 flavors. They were all pretty bad. I ended up buying bottles of about 6 or 8 different ones. They were really expensive - they only have large bottles 30 or 50 ml. Expensive mistake. The only one that was decent was some kind of vanilla cappuccino - that was okay.
