I have been thinking about lip balm tubes FOREVER! I can't decide if I want them or little jars, which I have used in the past. I like the jars but don't know how or what others think about them. Then I think I will use both...yeah, I know I overthink a lot of stuff when it comes to soaping, etc. I drive myself crazy at times! So, Zing please let us know how easy it is to fill them, and did you get plastic or cardboard-type ones, I am anxious to hear what you have to say about your experience! Have fun filling those little babies!
