I bought the tips from Sharon's daughter's site when I found out that Sharon no longer carried the. However, I can not seem to get the glue to come out of the very tiny metal tip. There were a couple of plastic lids with long tips that came with these metal tips. I just use them, since I can't seem to get the metal tip to work. You might check with Hobby Lobby or some craft store or site and find a long plastic tip that might work for you.She did advise NOT to use a metal pin in the glue tip when storing it, because it has a tendacy to rust and get into the glue -ask me how I know, I forgot and did that. She uses the plastic tips that come on a clothing tag that is attached to garments with the store price tag.
I guess there could be other things that work as well. Good luck. Perhaps you might find some tips on FaveCrafts.com.
