A glue gun is a handheld device used for dispensing hot glue, making it indispensable for crafting, repairs, and general bonding needs. It operates by heating glue sticks to a liquid state, which can then be applied to materials like wood, plastic, fabric, and metal. When the adhesive cools, it forms a strong bond, making it versatile for both permanent and temporary fixes.

Glue guns are available in both corded and cordless models, with options for high and low-temperature settings. Low-temperature glue guns are suited for delicate materials, while high-temperature models provide stronger bonds for tougher materials. Easy to use and portable, glue guns are widely used in arts and crafts, DIY repairs, and even light industrial applications.
