No. A glue gun is designed to accept and feed the correct size sticks only. Do not put mini glue sticks in a the wrong size glue gun, or try to force them to work. This will ultimately damage the glue gun, and the glue sticks will not feed properly.
If you are not sure what glue sticks that you should use, refer to the model number normally printed on the handle of your glue gun. Take a moment to research which sticks you should use, or give us a call and we will be happy to point you in the right direction. Call 1-877-770-5500, and a representative will assist you.
