If you've ever had to create multiple custom Liquid product templates to accommodate unique product data, you know how difficult it is to manage. I'll tell you how to do it easily :)
Metafields have four components: namespace, key, value, and description (optional). Namespaces will be used to group different metafields, keys will be used to reference our information, and values will contain our unique content. We can also specify if the value is a string or integer.
You can learn more about customizing metafields in our documentation page.
