Details of a product meta-field definition.

There are three fields in this definition:

1. Name
2. Namespace and key (the disabled one)
3. Description

Take the 2nd one - **Namespace** and **Key** separated by a period or full stop (.):

Namespace: _custom_

Key: _color_

These are the values we need for the meta-field configuration in **Final Invoice**.

Now, go to **Templates** in our app → click **Customize** → **Line items** → scroll down and check **Show product meta fields → Add property** and supply those values
