Review on Envelope Sealing Wax Seal Sticks For Mini Glue Gun, Pack Of 16 In Red by Greg Lockhart

I am using this product for glue gun "wax" to seal envelopes. This glue gun works fine and heats up fast and the stand is convenient, but on the 10-12th glue stick, the glue gun began to leak in the middle of the glue gun, filling the trough and dripping down the sides. I let it cool off and tried to heat to reuse and even though I squeezed the trigger, hot glue would not come out of the end of the gun, just dripped more out of the middle of the gun. The first gun was replaced quickly, but the same thing happened to the next gun, and I am unable to return the 2nd faulty glue gun. It may work fine for occasional use, but not for the long term use I need it for.
