PT-100 Pro-Tips, 12-/box
Place a Pro-Tip inside the spout for precise application of Hot Stuff CA Glue. To install, remove the spout from the bottle and cut down the tip so that the opening is large enough to slip the Pro-Tip through from the inside. Feed the Pro-Tip through from the inside so that the cone-shaped part fits snugly into the base of the spout and seals it off.
A Pro-Tip has the same diameter from its base to the tip, so if it clogs and you have to cut it down, it will still apply the glue just as precisely.
