Loctite gel control, ultra gel control and the like comes in this bottle with little squeezy bits on the sides. (There is a tube inside, btw, and the blue bits are squeezing the tube.)
It works really well because this glue is in gel form and it stays in place. The tiny tip means you can put it exactly where you want without mess getting all over. That also means less white fogging.
(Glue has its limitations, of course! Check these links for more glue and polymer clay earring info.)
