Hi,

Before you want to use the Elementor Product Brand, you need to create a new product attribute for Branding by following these steps:

1. Going to Product → Attributes, add new Attributes with Type: Images, then add some product brand & upload the brand image here,

2. Go to Products → All Products: then assign your product with the brand name you've to create on Step 1,

3. Navigate to Appearance → Customize → WooCommerce → Product → Brands: select the Attributes you've created on step 1 at Brand attribute.

4. Now you can use the Pencil Product Brand on Elementor to display a list branding of your products.
