I refill a Roxanne's basting glue bottle. I love the long thin tip that comes with it.

I've got glue with a long thin tip, and capillary action pulls the glue up. Not as bad as the usual plastic tip. That got gunked up so I shoved a straight pin in it and it rusted. I need a plastic pin. Toothpicks are too long, what else can you use?

I just use a cheap ink pen tip like Sharon Schamber said. I put a toothpick in it to keep it from drying.
