A glue gun is a very handy electrical appliance for those who wish to apply embellishments. Glue sticks are inserted in the gun and are then heated by the gun. You can then apply the glue in intricate places. To use the gun, you just push a glue stick into the glue stick feeder and squeeze the trigger. As you squeeze, the glue stick will travel down the barrel where it will melt and flow out of the nozzle. You can get both cold melt and hot melt glue guns/sticks.

Tip: Be careful not to touch the nozzle or the glue as it tends to get very hot.
