I went to the dollar store on the weekend and picked up a tube. The rubber foot is drying nicely as I type.
The weird thing about the super glue is that it came in a cylindrical container. The glue and the tip were separate when I got them. After screwing on the tip with the lid and using it, the glue does not fit in the container anymore.
Poor design. I'm not about to unscrew the tip and have super glue all over me. Instead, I had an empty mason jar that is now the super glue's new home.
