you can buy small empty plastic applicator bottles at the craft stores. they have the long applicator tips that you can cut off to give the size line of glue you need. i used a pin to poke a hole in the tip and got a very fine line that way. in some ways it works better than the metal tip. cause you can just repoke the hole when it clogs. the metal tip is very very tiny and can only be cleaned with the super fine wire that comes with it. and i lost the wire. so to clean the metal one now i have to wash it often in hot water. the plastic tips work just as well and fit on the glue bottle too or you can put some in the small bottle. the small bottle is a little easier to control for me.
