The Arrow GT21DT is a 20-watt dual-temperature mini hot glue gun that brings two heat settings to compact craft work. Dual-temperature control handles both delicate and stronger materials, so you can drop to low heat for fabrics, foam, and heat-sensitive crafts, then switch to high for tougher bonds, all in a small, easy-to-handle gun. A no-drip insulated nozzle prevents glue from dripping onto your work surfaces and helps keep projects clean, while the comfortable, lightweight ergonomic design keeps it easy to control through detailed work. It uses Arrow 5/16-inch mini glue sticks, making it a versatile pick for crafts, fabric projects, upholstery touch-ups, and household repairs. The dual-temp feature is unusual in a mini gun and makes this a strong choice when your projects range from delicate to sturdy. Corded power keeps heat consistent with no battery to recharge.
