Those tips are hard to find. Two suggestions: Roxanne Glue-Baste-It comes with the tip. It is expensive but you can use Elmer's after you use up the Roxanne. Less expensive and works quite well, is the Elmer's Dual Tip Pen. The only place I could find that was Walmart but the finer end of that is pretty good and you can't beat the price.
okay I have this but I can't get the tip clean after using it. I tried sticking a long straight pin in it and I tried soaking in hot water, still is clogged. Anybody know how to clean the tip??
