Dollar Tree recalls more than 1 million hot glue guns after fires

Discount retailer Dollar Tree is recalling more than 1 million Crafter's Square Glue Guns sold nationwide because they can malfunction when plugged in, potentially burning people and property.

People should unplug and stop using the recalled product, which sold for about $1 and can be returned to any Dollar Tree or Family Dollar store for a full refund, Dollar Tree said Thursday in a notice posted by the U.S. Consumer Product Safety Commission. 

The company has received seven reports about the hot glue guns, including four fires and one involving irritated skin.
