If the glue gun will be colored in the future, make sure to use separate guns for standard glue and colored glue. Nice to use, not as bright at the end of the cure as one would expect. Very fun to use on wands and lightsabers. CONS: Need your own gun so it doesn't stain any future glue sticks that aren't as bright after curing. Pros: Fun and makes a great lightsaber decor. fun to use. Let the kids go, "WAOOAHHHWYYY"
