Awesome set of Backflow Incense Cones!

These cones are great. The colors are bright and vibrant. They light easily and burn smoothly. They do not crumble while burning and the smoke flows freely from the backflow. Works with any standard backflow burner. The scents are not marked or separated out and some of them are little hard to distinguish, however the listing does have a chart that lists them by color. They do not include this chart in your packaging though. But aside from that small annoyance, I love these backflow insence cones.
