The set is complete, with all tubes, caps and clips in place. It still has the cardboard insert for the tubes and the advertising sheet that came with it. These lights are unique in that the tubes contain 2 different liquids, much like "shooting stars" and Telsen bubble lights from the 1950s.
When they start bubbling, they resemble miniature lava lights. The bases have removable covers so that you can easily change the bulbs when they burn out. I have installed US 110V C6 lamps and fitted the string with a regular US plug. The original UK plug is included. They were only used by us for a couple of seasons, and always with a dimmer.
The box is in really good shape as well, with the exception of a tear inside the bottom part, which you can see in one of the photos. The corners are intact and the top and bottom are solid.
