The Gold Number 3 Iron-On Fabric Patch is a gold-finished, number-shaped iron-on patch that attaches to fabric using heat applied with an iron or heat press, eliminating the need for sewing. It's commonly used to personalize sportswear, backpacks, or t-shirts with a chosen number, creating a decorative effect similar to a personalized sports jersey. The number 3 is a common choice in sportswear, often associated with football teams and other team sports.
