This is something I wish I had purchased years ago. The glue stays on the tip until touched to the model and places it right where you want it. This tool makes c/a gluing a lot less messy and gives your model a much more professional look when finished. It works best for me when putting a small bead of c/a on each part edge then let dry, next assemble the parts and touch this applicator to the seam and let capillary action do the rest. If the tip gets clogged just dip it in the c/a glue again and it will loosen it up quickly. Worth the money and makes gluing cleaner.
