I would also have to say they are not that bad, the globes were sold as Groove Tubes, Link'd, Crayola and Oozy Flo. The glitters are some of the best flowing I have ever seen, the lavas look like hell when they are cold but once warm they flow fine. I have had several lavas and glitters for some years now and they all work fine. They use a standard bottle cap so they would be easy to refill if needed.
